Answer:
y = - 2x + 6
Step-by-step 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, 6) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = =
= - 2
The line crosses the y- axis at (0, 6 ) ⇒ c = 6
y = - 2x + 6 ← equation of line
