Answer:

Step-by-step explanation:

(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)

$Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4$

m = 4

y - y₁ = m (x - x₁)

y - [-2] = 4(x - [-1])

y + 2 = 4(x + 1)

y + 2 = 4x + 4

y = 4x + 4 - 2

y = 4x + 2
