Answer:

y =
(4)/(5) 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 ) = (0, 4 ) and (x₂, y₂ ) = (5, 8) ← 2 points on the line

m =
(8-4)/(5-0) =
(4)/(5)

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

y =
(4)/(5) x + 4 ← equation of line
