Question

What is the slope of the line passing through the following points: #(-2,-7) , (-7,0) #?

Answer 1

`-7/5`

Explanation:

to calculate the slope of a line (m) use the gradient formula :

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

in this question let `(x_1 , y_1) =(- 2 ,- 7 ) (x_2 , y_2) = ( -7 , 0 )`

substitute these values into the formula as follows :

`m =( 0 -(- 7))/((- 7) - (- 2)) = 7/-5`

`rArr m = slope = -7/5`
