The line of best fit will increase from left to right. D. The line of best fit will decrease from left to right.
Answer:
B
Step-by-step explanation:
The line of best fit should be vertical. This answer may not be correct.
The correct statement is statement B that is the line of best fit will be vertical.
What is a scatter plot ?
A scatter plot is a graph in which the values of two variables are displayed along two axes, and any correlation is revealed by the pattern of the resulting points.
It is given that , after a particular amount of hours of sunlight, Erika made a scatterplot showing the height that a plant increased to. On the horizontal axis, the plant height was shown.
We know that in a scatter plot , the values of two variables are displayed along two axes. As the plant height was shown on the horizontal axis. The other value which is amount of hours of sunlight will be on the vertical axis.
So , the statement which best describes how Erika should draw her line of best fit i.e., the line of best fit will be vertical.
Therefore , the correct statement is statement B that is the line of best fit will be vertical.

Graph each function for the given domain.
3x - y = 1 D(-3,-1,0,4)
Answer:
the following ordered pairs are your coordinates: (-3,-10), (-1, -4), (0,-1), (4,11)
Step-by-step explanation:
We can find these algebraically. First, you need to put your equation into the form y=mx+b. The m is the slope and the b is your y intercept. Once we have that equation, we just plug in the given X values to find their Y counterparts. The domain is simply the X coordinate and the range is the Y. I hope this helps!

the ratio of 3 numbers is 2:3:4. If the sum of the numbers is 108, find the numbers. NEED ANSWERS ASAP
Step-by-step explanation:
x + y + z = 108
x/y = 2/3
y/z = 3/4
x = 2y/3
z = 4y/3
we use these 2 as substitute in the first equation
2y/3 + y + 4y/3 = 108
2y + 3y + 4y = 324
9y = 324
y = 36
x = 2y/3 = 2×36/3 = 2×12 = 24
z = 4y/3 = 4×36/3 = 4×12 = 48

i need help, can someone show me how to solve it
Answer:
9
Step-by-step explanation:
Simply plug -3 in for x.
-2(-3)^2-7(-3)+6
(-3)^2=9
9*-2= -18
-7*-3=21
-18+21=3
3+6=9
Answer:
f(-3) = 9
Step-by-step explanation:
Here we have a quadratic function in x: and we want to know the value of this function when x = -3.
Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to f(-3) = -2(9) + 21 + 6, or
f(-3) = -18 + 27 = 9
Thus, f(-3) = 9
