Answer:

(2,0) - x -intercept

(0, 1.5) - y-intercept

Explanation:

The slope of the points can be found by writing a ratio of vertical change to horizontal change. It can be found in the table by subtracting y values from each other and subtracting x values from each other. The y values decrease by 3 each time or -6 - -3 = -6 + 3 = -3.

The x values increase by 4.

So the rate of change is -3/4.

This means if you go backwards on the table the previous point would be (2, 0). This is the x-intercept.

To find the y-intercept, you must go further back. Going back 2 more units would make the table appear as:

x y

-2 3

0 ???

2 0

6 -3

10 -6

14 -9

Since the y values decrease by 3 each time and we went back half the usual amount, then the value would be 1.5.
