Question

A line with a slope of the -5 passes through the points (-4, s)and (-7, 6). What is the value of s ?

Answer 1

Explanation:

Set up the slope formula to solve for the unknown:

`(6-s)/(-7-(-4))=-5` which simplifies to

`(6-s)/(-7+4)=-5` which simplifies a bit more to

`(6-s)/(-3)=-5` Multiply both sides by -3 to get rid of the fraction, leaving you with:

6 - s = 15 and

-s = 9 so

s = -9
