(-2, -5) and (12, -1) determine the slope of the line that passes through these points

Answer 1

Slope formula using two coordinate points:

m = (y₂ - y₁)/(x₂ - x₁)

Label the coordinates:

(-2, -5) and (12, -1)

x1 = -2

y1 = -5

x2 = 12

y2 = -1

m = (-1 - -5)/(12 - -2) Hint: - (-5) = 5

m = (-1 + 5)/(12 + 2)

m = 4/14 Find common factor of 2

m = 2/7

Answer 2

m = (- 5 + 1) / (-2 - 12)
