Question

Use the slope formula to find the slope of the line through the points P1 and P2.P1= (8,-9)P2 = (-3,4)

Answer 1

To answer this question we will use the following formula for the slope of a line that passes through (x₁,y₁) and (x₂,y₂):

`m=(y_2-y_1)/(x_2-x_1)\text{.}`

Substituting (x₁,y₁)=(8,-9) and (x₂,y₂)=(-3,4) in the above formula, we get:

`m=(4-(-9))/(-3-8)\text{.}`

Simplifying the above result we get:

`m=(4+9)/(-11)=(13)/(-11)=-(13)/(11)\text{.}`

Answer:

`-(13)/(11)\text{.}`
