Question

Choose the graph which matches the following system of equations.

x – 3y = –12
2x – y = 1

Answer 1

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.

Answer 2

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?

Answer 3

The slope is 2, and the y-intercept is -1.

Answer 4

I'm just having trouble with the first equation, getting it into slope intercept form.

Answer 5

x – 3y = –12
3y = x+12
y = x/3+4
