intercepts and graphs

Question

Identify each point as an x-intercept, y-intercept, or neither



1. (-8,-9)
2. (0,-7)
3. (-3,0)

Answer 1

An intercept is where a graph crosses and axis.

The y intercept is where the graph crosses the y axis. If a point is on the y axis, the x coordinate is ZERO. Therefore, (0,-7) is the Y INTERECEPT

The x intercept is where the graph crosses the x axis. If a point is on the x axis, the y coordinate is ZERO. Therefore, (-3,0) is the X INTERECEPT

The remaining choice is NEITHER, since there is no coordinate that is zero.
