Y = 8x - 2
y = 9x - 7
8x - 2 = 9x - 7
- 8x - 8x
-2 = x - 7
+ 7 + 7
5 = x
y = 8x -2
y = 8(5) - 2
y = 40 - 2
y = 38
(x, y) = (5, 38)
The answer is C.

The standard form of any linear equation with two variables is

, where a, b, and c are constants. To convert this equation to standard form, simply subtract

from both sides to get

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get
