Question

What is the slope of the line that passes through (2, -3) and (9,-7)?

Answer 1

See a solution process below:

Explanation:

The slope can be found by using the formula:

`m=(y_(2)-y_(1) )/(x_(2)-x_(1) )`

Where m is the slope and ( x) and ( ) are the two points on the line.

Substituting the values from the points in the problem gives:

`m=(y_(2)-y_(1) )/(x_(2)-x_(1) )=(-7-(-3))/(9-2)= (-4)/(7)=-(4)/(7)`
