Question

What is the equation of this graphed line

Answer 1

y= -9/8x+7

Explanation:

find the slope

y2-y1/x2-x1

-2-7/8-0

-9/8

y=mx+b

m=slope

b=y intercept

y= - 9/8x + b

y= -9/8x+7

Answer 2

Answer: y = -9/8 + 7

Explanation:

point a = (0,7), point b = (8,-2)

y = mx + b

b = 7

y = mx + 7

-2 = 8m + 7

-9 = 8m

m = -9/8

y = -9/8 + 7
