What is the x-intercept of a linear graph?

• The x-intercept of a linear graph is the point where the graph intersects the x-axis.

• The x-intercept of a linear graph is the highest point on the graph.

• The x-intercept of a linear graph is the point where the graph intersects the z-axis.

• The x-intercept of a linear graph is the point where the graph intersects the y-axis.

What is the y-intercept of a linear graph?

• The y-intercept is the point where the line touches the y-axis and is at the point (0, b)

• The y-intercept is the slope of the graph at the point (0, b).

• The y-intercept is the point (a, 0), where a is the value of x when y is 0.

• The y-intercept is the highest point on the graph.
