Question

Please help me, thank you.

Answer 1

y = 2x - 3

Explanation:

Take any tow point from the line

(x₁ , y₁) = (1 , -1) & (x₂ , y₂) = (0 , -3)

`Slope = (y_(2)-y_(1))/(x_(2)-x_(1))\\\\`

`= (-3-[-1])/(0-1)\\\\=(-3+1)/(-1)\\\\=(-2)/(-1)\\\\=2`

m = 2 & (1, -1)

y - y₁ = m(x -x₁)

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

y + 1 = 2x - 2

y = 2x - 2 - 1

y = 2x - 3
