4  x - 9 y = 1
- 4 x + 6 y = - 2 

- 3 y = - 1 
y = 1 

4 x - 9 y = 1
4 x - 9 ( 1) = 1
4 x - 9 = 1
4 x = 1 +9
4 x = 10 
x = 10/4 = 2.5

First, find the slope. 6/3 = 2/1 = 2. m = 2.

Next, find the y-intercept. In this case they gave it to you directly. b = -3.

So, the equation would be y = 2x - 3.
