Question

What is the slope of the line that passes through the given points? (-1, -5) and (-12, -5)

Answer 1

First, find the slope (m) using the formula: $\frac{y2 - y1}{x2 - x1}$

m = $\frac{-5 - (-5)}{-1 - (-12)}$ = $\frac{0}{11}$ = 0

Next, input the slope and ONE of the points into the point-slope formula:

y - y₁ = m(x - x₁)   ; where (x₁, y₁) is the chosen point

y - (-5) = 0(x - (-1))

y + 5 = 0

y = -5

Answer: y = -5
