Question

What is the slope of the line that contains the points (3,-8) (-7,-4)?

Answer 1

Slope `=-2/5`

Explanation:

Given -`(3,-8) (-7,-4)`

Let -

`x_1=3`
`y_1=-8`
`x_2=-7`
`y_2=-4`

Then the formula to calculate slope is-

`(y_2-y_1)/(x_2-x_1)=((-4)-(-8))/((-7)-3)=(-4+8)/(-7-3)=4/(-10)=-2/5`

Slope `=-2/5`
