Answer:

y =
(2)/(3) x + 4

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 ) = (- 6, 0 ) and (x₂, y₂ ) = (0, 4 ) ← 2 points on the line

m =
(4-0)/(0-(-6)) =
(4)/(0+6) =
(4)/(6) =
(2)/(3)

The line crosses the y- axis at (0, 4 ) ⇒ c = 4

y =
(2)/(3) x + 4 ← equation of line
