Answer:
y = 2x + 5
Step-by-step explanation:
(-1 , 3) & (2 , 9)
x₁ = -1 ; y₁ = 3 & x₂ = 2 ; y₂ = 9
[tex]slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{9-3}{2-[-1]}\\\\=\dfrac{6}{2+1}\\\\=\dfrac{6}{3}\\\\= 2[/tex]
m = 2 & (-1 , 3)
Equation of line:
y - y₁ = m(x - x₁)
y - 3 = 2(x - [-1])
y -3 = 2(x + 1)
y - 3 =2x +2
y = 2x + 2 + 3
y = 2x + 5
