Answer:
y = -
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2points on the line
m =
= -
Note the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = -
x + 3 ← equation of line
