3. Which of the following points on the xy-graph is the x-intercept of the
equation y=2x-8?
A. (0,4)
B. (0,5
C. (4,0)
D.(-4,0)
E. (-1,0

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
