This table gives a few (x,y)(x,y)left parenthesis, x, comma, y, right parenthesis pairs of a line in the coordinate plane.
xxx yyy
-21−21minus, 21 -64−64minus, 64
-15−15minus, 15 -48−48minus, 48
-9−9minus, 9 -32−32minus, 32

Answer:

(3,0)

Step-by-step explanation:

You want the x-intercept so you have to find the values until the x value is 0 or above. If you put the points into a chart it will look like this:

x   l   y  

-21 l -64             You add 6 to each x value to get the next value. -15+6=-9

-15 l -48             You add 16 to each y value to get the next value. -48+16=-32

-9  l -32              -9+6=-3         -32+16=-16  

-3  l -16               -3+6=3          -16+16=0

3  l  0

The answer is (3,0). I got it right on Khan Academy.
