Answer:
(0, 12 ) and (4, 0 )
Explanation:
the y- intercept is the point on the y- axis where the line crosses.
the x- coordinate of any point on the y- axis is zero
substitute x = 0 into the equation and solve for y
y = - 3(0) + 12 = 0 + 12 = 12 ← y- intercept , then
y- intercept is (0, 12 )
the x- intercept is the point on the x- axis where the line crosses
the y- coordinate of any point on the x- axis is zero
substitute y = 0 into the equation and solve for x
0 = - 3x + 12 ( subtract 12 from both sides )
- 12 = - 3x ( divide both sides by - 3 )
4 = x ← x- intercept , then
x- intercept is (4, 0 )
