Answer:
x-intercept = (9, 0)
y-intercept = (0, 21)
Explanation:
x-intercept
The x-intercept of a linear graph is the point at which the line intersects the x-axis, so when y = 0.
Therefore, to find the x-intercept, substitute y = 0 into the equation and solve for x:

Therefore, the x-intercept of the given equation is (9, 0).

y-intercept
The y-intercept of a linear graph is the point at which the line intersects the y-axis, so when x = 0.
Therefore, to find the y-intercept, substitute x = 0 into the equation and solve for y:

Therefore, the y-intercept of the given equation is (0, 21).
