First, find the slope (m) using the formula: [tex] \frac{y2 - y1}{x2 - x1} [/tex]
m = [tex] \frac{-5 - (-5)}{-1 - (-12)} [/tex] = [tex] \frac{0}{11} [/tex] = 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
