Question

Whats the equation for the slopes (-3,12) (5,2)

Answer 1

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{2 - 12}{5 - (-3)} = \frac{-10}{5 + 3} = \frac{-10}{8} = -1\frac{1}{4}$

y - y₁ = m(x - x₁)
y - 2 = -1¹/₄(x - 5)
y - 2 = -1¹/₄(x) + 1¹/₄(5)
y - 2 = -1¹/₄x + 6¹/₄
  + 2             + 2
     y = -1¹/₄x + 8¹/₄
