Question

Graph the vertical line x = 7. Then name its intercept.
A) x -intercept = 7 
B) y -intercept = 7 
C) x -intercept = 7 
D) y -intercept = 7

Quizplus · Accepted Answer

The equation x = 7 creates a vertical line on the x-axis at the point (7, y). Since the line is vertical, it does not intersect the y-axis, so there is no y-intercept. Therefore, the intercept being referred to in the question must be the x-intercept, which occurs when the line crosses the x-axis. Since this line never crosses the x-axis, it has no x-intercept.
