Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)

Answers

Answer 1

Answer: y = -3.5x - 4.5

suppose: the equation of the line is y = ax + b ( a ≠ 0 )

because the line passes through (-2;2.5) => 2.5 = -2a + b

the line passes though (0;-4.5) => -4.5 = b

=> b = -4.5

   2.5 = -2a + b

=> a = -3.5

    b = -4.5

=> the equation of the line is y = -3.5x - 4.5

Step-by-step explanation:

Answer 2
The equation Of the line is y =-3.5x-4.5

Margie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?

Answers

Answer:

She spent $5.05 for her total purchase.

Step-by-step explanation:

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.

Lastly, Add it all up, 3+0.4+1.65=5.05

is there a graph or something? or are you supposed to write it out as an equation, cuz if so its p-4

Answer:

p - 4

Step-by-step explanation:

when it says "the difference" its a subtraction

when it says "of ___ and ___" the subtraction is between these two number; therefore the expression is p - 4

if it had said "the sum" it will be addition

if it had said "the product" it will be multiplication

1. Which is the slope of the line that passes through the points (1,1) and (2,7) ?

1a. Pick a point the line passes through above and with the slope you calculated, find the y- intercept

1b. Now that you know the y- intercept, what is the equation of the line ?

Answers

Hello!

1)First, they ask us to find the slope. [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex] is the slope formula.

The slope is 6

2)Let's just use the point they gave us (1,1)

We need to substitute the point in the equation and solve.  

The y-intercept is -5

3) y=mx+b (m=slope b=y-intercept)

y=6x-5

Write an equation in slope-intercept form of the line shown.

Answers

Answer:

Step-by-step explanation:

y2-y1/x2-x1

1+3

3-1

your slope is 4/2 or 2. keep going down to find what y is when x is 0, which happens to be -5

so now you have a slope and a y intercept you can solve  like y=mx+b where m is your slope and B is your y intercept

y=2x-5 is your answer

it’s y=2x-5 because if you go down to see where the y intercept is which is where the line meets the y axis (the vertical axis) which is on 0,-5 which would be the b i think in y=mx+b

Perform the indicated multiplication: 2 - 3x - 12 = 9 - 3x

Gather all the x terms on one side and all the constants on the other:

since this is never true, 2 - 3x - 12 = 9 - 3x has no solution.

Solve the system by substitution.
9x + 7y = 33
-6x = y

Answers

Answer:

x= -1, y= 6

Step-by-step explanation:

9x + 7y =33---a

-6x = y---b

Put b into a,

9x + 7(-6x) = 33

9x - 42x = 33

-33x = 33

x = -1----c

put c into b,

-6(-1) = y

y=6

Answer:

The answer is (-1, -6)

Step-by-step explanation:

To get y by itself, you switch sides of the Y and the -6x

9x+7y=33

y= -6x

You then put the -6x where the y is

9x+ 7(-6x) = 33

9x -42x =33         9 -42 = -33

-33x = 33

It's now a one-step equation

x= -1

Now you put  the x value (-1) where the x is in y= 6x

y= 6 (-1)    y=-6
