Answer:

y = -14/17x -7/17

Explanation:

m = rise/run

m = (y2-y1)/(x2-x1)

m = (7-(-7)) / (-9-8)

m = 14/-17

we will plug the slope into y=mx+b

x= 8

y= -7

-7 = (14/-17)*(8) + b

b = -7/17

Answer:

y = -14/17x - 7/17

Explanation:

y2 - y1 / x2 - x1

7 - (-7) / -9 - 8

14/-17

= -14/17

y = -14/17x + b

-7 = -14/17(8) + b

-7 = -112/17 + b

-7/17
