Question

Determine the slope of the line that passes though the points (2,-5) and (4,3).

Answer 1

Answer: slope = 2

Explanation:

The formula for calculating slope is given as :

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

`x_(1)=2`

`x_(2)=4`

`y_(1)=-5`

`y_(2)=3`

substituting into the formula , we have :

`m = (3-(-5))/(4-2)`

`m = (8)/(2)`

`m = 2`

Therefore : slope = 2
