Question

A line that includes the points (-9,-5) and (-10, j) has a slope of -10. What is the value of J

Answer 1

j = -15

Explanation:

Given that,

A line that includes the points (-9,-5) and (-10, j) has a slope of -10.

The slope of a line for which two points are given is :

`m=(y_2-y_1)/(x_2-x_1)\\\\-10=(j-(-5))/(-10-(-9))\\\\10=(j+5)/(-10+9)\\\\10=(j+5)/(-1)\\\\-10=j+5\\\\j=-10-5\\\\j=-15`

So, the value of j is equal to -15.
