Question

What is the slope of the line containing (-3,1) and (1,-2)

Answer 1

Hello!

The formula for the slope is seen below.


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

The twos and ones represent either one of the y-values or x-values on the line. Any ordered pair can represent the ones or twos and the slope will be the same.

We will have (-3,1) be (
`x_(1) , y_(1)`) and (1,-2) be (
`x_(2) y_(2)`). We will plug these numbers into the equation.


`(-2-1)/(1+3) = -(3)/(4)`

Therefore our slope is
`- (3)/(4)`.

I hope this helps!
