In a coordinate plane, what is an x-intercept?

• A. The point where the graph crosses the x-axis (y = 0)
• B. The point where the graph crosses the y-axis (x = 0)
• C. The slope of the line
• D. The maximum value of the function

Answer: (A)

An x-intercept is the point where the graph meets the x-axis, which means the y-coordinate is zero. So the intercept is the point (x, 0). That’s why it’s described as the point where the graph crosses the x-axis (y = 0). The other ideas refer to different features: crossing the y-axis happens when x = 0 (the y-intercept), the slope is how steep the line is, and the maximum value is unrelated to where the graph hits the axis.
