Use the slope formula to find the slope of the line through the points (−3,−6) and (0,3).

liubo4ka [24]

Slope= y/x so first let’s find the difference in the y coordinates. -6 and 3. -6 + 9= 3
So far we have 9/x, now on to the x coordinates. -3 and 0, -3 + 3 = 0
9/3 is the slope
now simplify and the slope is 3
