Answer:
slope = m , m = rise / run rise = change in y run = change in x
Step-by-step explanation:
to find change in y just subtract the second y from the first , like thus,
P1=(-10,8) = (X1,Y1)
P2=(-15,-7) = (X2,Y2)
-7-8=-15= change in Y
to find the change in X just subtract the second x from the first, like thus,
-15-(-10) = -15+10 = 5
m= -15/5
m=-3
it's a slope of negative 3... make sense?
