7
)
(5,−7)left parenthesis, 5, comma, minus, 7, right parenthesis?

Answer 1

The slope is

`- (3)/(2)`

Explanation:

Remember:

`Slope = (y_2 - y_1)/(x_2 - x_1)`

All we have to do is plug the points in.

`Slope = ( - 7 - ( - 1))/(5 - 1) = ( - 6)/(4) = - ( 3)/(2)`

Therefore, your slope is

`- (3)/(2)`
