Find the equation of a line that passes through the points (-1,-3) and (1,-5).
The equation of the line is (y + x = 0).
What exactly do you understand by slope?The slope of a line indicates its steepness in addition to its direction.
A line's slope is defined as the change in y coordinate in regards to a change in x coordinate.The total increase in y coordinates is Δy, while it is x in Δx coordinates.As a result, the y coordinate shift in relation to the x coordinate shift could be written as,m = Δy/Δx
where, m is the slope
And, tan θ = Δy/Δx
The above tan is also known as the line's slope.
The slope of a line can also be calculated just using two straight line points. The slope of line formula could then be used with two point coordinates.
Now, in response to the question;
P₁ = (x₁, y₁)
P₂ = (x₂, y₂)
Then slope will be;
Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)
Consider the values given in the question;
(x₁, y₁) = (-1,-3) and,
(x₂, y₂) = (1,-5).
Put the values in the formula of the slope;
Slope = m = (-5 + 3)/(1 + 1)
m = -2/2
m = -1
Thus, the slope of the line is -4.
Now, the formula for finding the equation of line using the two points system.
(y - y₁) = m(x - x₁)
(y + 3) = (-1)(x + 1)
y + 3 = -x - 1
y + x + 4 = 0.
Therefore, the equation of the line using two point system is calculated as (y + x = 0).

The length of a bacterial cell is about 5.36 x104 m, and the length of an amoeba cell is about 6.2 x 104 m.
The length of a bacterial cell is about 5.36 x104 m, and the length of an amoeba cell is about 6.2 x 104 m.
Thus length of a bacterial cell is 0.864 times of length of an amoeba cell.
Given that the length of a bacterial cell is about 5.36 x 10⁻⁴ m, and the length of an amoeba cell is about 6.2 x 10⁻⁴ m.
Ratio of the size of the cell is
B/A = 5.36 x 10⁻⁴/6.2 x 10⁻⁴
B/A = 5.36/6.2
= 0.864
Thus length of a bacterial cell is 0.864 times of length of an amoeba cell.

the pawn class represents the physical body, and the controller class represents the brain. choose one • 1 point true false
Actors that can be manipulated by humans or artificial intelligence (AI) all descend from the Pawn class. A player or AI entity's physical representation in the world is called a "Pawn." This means that the player's or AI entity's physical interactions with the outside environment, such as collisions and other physical interactions, are likewise controlled by the Pawn. This can be perplexing in some situations because some game types might not have an obvious player mesh or avatar. Regardless, the Pawn continues to reflect a player or other entity's actual position, rotation, etc. within the game. A unique class of Pawn that can move around is called a Character.
The default relationship between Controllers and Pawns is one to one, which means that each Controller can only have one Pawn under their control at any given moment. Additionally, a Controller does not necessarily hold a Pawn that spawns while a game is being played.

write the equation in slope intercept form for the line with the given slope that contains the given point l.
slope =-3;(-1,6)
Answer: 3 = b (maybe, usually unsure)
Step-by-step explanation: bing
y = mx + b, this is the formula.
b = y-intercept
m = slope
1. We know that (-1,6) is our pair.
2. The formula when written with the info is y = -3x + b
3. We know that -1 is the x and the y is 6, so subbing the x and y in the formula, it is 6 = -3(-1) + b.
4. When multiplied, it becomes 6 = 3 + b
5. Then we combine like terms, by subtracting 3 into 6, making 3 = b
6. So, it is 3 = b

2. Provide all the details necessary to map △XYZ to △JLK in the picture below. Show your work AND record your response below.
Translate △XYZ 9 units to the right and then 11 units down to get △JLK.
We need to map △XYZ to △JLK.
From the figure, △XYZ is in the 2nd quadrant and △JLK is in the 4th quadrant.
Also it is clear that side XY is mapped to JK, YZ to KL and XZ to JL.
To find the distance translated to the right we need to find the distance between the x- coordinates of the corresponding points of the two triangles as they are congruent.
Consider Y and K. The x- distance between Y and K = 6 - - 3 = 9 units.
So first 9 units translation to right.
Similarly, To find the translation downwards, we need to find the distance between the y-coordinates of Y and K.
y-Distance between Y and K = 1- -10 = 11 units.
So next 11 units translation to down.
This will give the △JLK from △XYZ .

The average rate of change of the function over the interval is 8(b + 1)
How to determine the average rate of change of the function over the interval?The given parameters are
Function: f(x) = 8x^2 - 6
Interval: [1, b]
Calculate f(1) and f(b) using the function definition
So, we have
f(1) = 8(1)^2 - 6 = 2
f(b) = 8(b)^2 - 6 = 8b^2 - 6
The average rate of change of the function over the interval is then calculated as
Rate = [f(b) - f(1)]/[b - 1]
This gives
Rate = [8b^2 - 6 - 2]/[b - 1]
Evaluate
Rate = [8b^2 - 8]/[b - 1]
Factorize the numerator
Rate = [8(b + 1)(b - 1)]/[b - 1]
Divide through by b - 1
Rate = 8(b + 1)
Hence, the average rate of change of the function over the interval is 8(b + 1)

Th number of tiles the students need is 512.
How many tiles are needed?The first step is to convert feet to inches
1 feet = 12 inches
The next step is to convert the dimensions of room 111 to inches
8 x 12 = 96 inches
16 x 12 = 192 inches
Now, determine the area of the room and the tiles.
Area = length x width
Area of the room = 96 x 192 = 18,432 in²
