Question 4 • Modern Math KHS

Determine the x- and y- intercepts for the graph defined by the given equation.x = -9

Answer
A
x-intercept is ( -9, 0) No y-intercept
B
No x-intercepty-intercept is ( -9, 0)
C
No x-intercept y-intercept is (0, -9)
D
x-intercept is (0, -9) No y-intercept

Explanation

The equation x = -9 describes a vertical line where every point has x-coordinate -9. It crosses the x-axis, where y = 0, at (-9, 0). It never crosses the y-axis, where x = 0, so the correct choice is “x-intercept is (-9, 0); no y-intercept.”
