Answer:
y = 4x - 3
Explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m =
= 4
The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3
y = 4x - 3 ← equation of line
