blagie [28]

Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

the two points from the graph are

(4,40) and (7,70)

substitute the values in the formula

m=\frac{70-40}{7-4}\\m=\frac{30}{3}\\m=10

therefore

Write the equation of the line that passes through the points (2, 1) and (-8,-8).
nordsb [41]

Answer:

y = 0.9x - 0.8

Step-by-step explanation:

First you use the formula m = (y2-y1) / (x2-x1)

Sub in the 2 points you are given and you get m = (-8-1) / (-8-2)

m = -9/-10 = 9/10

Now u use the point slope formula, (y - y1) = m(x - x1)

Sub in the points and you get (y - 1) = 9/10 (x-2)

Expand it out to get y - 1 = 9/10x - 18/10

multiple everything by 10 = 10y - 10 = 9x -18

make y the subject, 10y = 9x - 8

y = 0.9x - 0.8
