Question

Find the equation of the line shown in the
graph below.

Answer 1

y = 2x - 1

Explanation:

Point 1: (0, -1); Point 2: (1, 1)

(x₁, y₁) (x₂, y₂)

y₂ - y₁ 1 - (-1) 1 + 1 2

---------- = --------- = -------- = ------ = 2

x₂ - x₁ 1 - 0 1 1

y - y₁ = m(x - x₁)

y - (-1) = 2(x - 0)

y + 1 = 2x - 0

-1 -1

-----------------------

y = 2x - 1

I hope this helps!
