$-7/5$

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 :

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

$rArr m = slope = -7/5$

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