Answer:

y =
(3)/(2) x - 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 =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m =
(0-(-3))/(2-0) =
(0+3)/(2) =
(3)/(2)

the line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y =
(3)/(2) x - 3 ← equation of line
