To tackle this problem, first try rewriting the 2 equations in slope intercept form (remember, y=mx+b). Remember b is the y intercept, which means, the y value when x=0, and that m is the slope, and is vertical change/horizontal change.
To get you started, take a look at the 2nd equation. 2x-y=1. Add y to both sides, and subtract 1 from both sides. Now it is in slope intercept form. y=2x-1. What is the slope, and what is the y intercept?

Other answers:

The slope is 2, and the y-intercept is -1.
I'm just having trouble with the first equation, getting it into slope intercept form.
x – 3y = –12 3y = x+12 y = x/3+4
thanks muchos
