Answer:
(3,0)
Step-by-step explanation:
The x-intercept of the line is where the line crosses the x-axis and the y-value is 0.
This line has a slope of
[tex]m = \frac{y_2-y_1}{x_2-x_1}= \frac{-48--64}{-15--21} =\frac{-48+64}{-15+21} =\frac{16}{6} =\frac{8}{3}[/tex]
This means that when -32 becomes -32+8=-24 then its x-value is -9+3 = -6.
Continue this pattern until the y value is 0.
-32+8 = -24 and -9+3 = -6
-24+8 = -16 and -6+3 = -3
-16 + 8 = -8 and -3+3=0
-8+8=0 and 0+3 = 3
The x intercept is (3,0).
