Question

Find the slope of the line through the given points

(-9,-3), (-14,16)

(18,-5) (18, 2)

(-15,-18) (-11,-2)

(-10,-11) (-4,-2)

(-20,-10) (6,2)

Answer 1

I can’t solve all of them but maybe one and I will give you the formula for you to solve the rest.
Slope = (y2 -y1) / (x2 -x1).
m= ( 16 -(-3)) / ( -14 -(-9))
m = (16+3)/(-14+9)
m = 19/ -5
