Answer:

x = 3

Explanation:

slope =
(y_(2) - y_(1) )/(x_(2) -x_(1) )

Using the your two points the slope = m =
(-8 + 5)/(7-x) = (-3)/(4)


(-3)/(7-x) =(-3)/(4)

Since the numerators are equal, then the denominators must be equal.

So, 7 - x = 4

-x = -3

x = 3

Answer:

we have

slope=(-5--8)/(x-7)

-3/4=3/(x-7)

-3(x-7)=3×4

-3x+21=12

21-12=3x

3x=9

x=9/3=3
