Question 150559: I'm supposed to put the following formulas in y=mx+b form. Then I'm supposed to plot the Y intercept. Then to get the 2nd point I need to plot the rise and run of the two formulas. Last I need to give the point at which the two lines intersect. When I try these steps, it's not coming out right on my graph.

Plot the intersect points of the two equations
2x + y = 4
3x - 4y = 6
Answer in book is (2,0)
When I change the equations I get the following;
y = -2x/1 -4
y = 3/4x - 6/4 (I divided equation by -4 to get this solution)

Plot the intersect points of the two equations
x + 3y = -6
x - 3y = 0
Answer in book is (-3,-1)
When I change the equations I get the following;
y = -1/3x - 2 (I divided equation by 3 to get this solution)
y = 1/3x + 0 (I divided equation by -3 to get this solution)

Plot the intersect points of the two equations
3x - 2y = -6
-6x + 4y = 9
Answer in book is No solution
When I change the equations I get the following;
y = 3/2x + 3 (I divided equation by -2 to get this solution)
y = 3/2x + 9/4 (I divided equation by 4 to get this solution)

Plot the intersect points of the two equations
x + 2y = 4
-2x - 4y = -8
Answer in book is Infinite
When I change the equations I get the following;
y = -1/2x + 2 (I divided equation by 2 to get this solution)
y = 1/-2x + 2 (I divided equation by -4 to get this solution)
