Which of the following values for c would mean that the system of equations 2x − 3y = 1 and cx − 3y = 2 would not have any solutions?

a.2
b.3
c.1
d.0

If  the L.H.S would be equal for both equations, and R.H.S would be unequal, then they don't have any solution, 
so,c = 2

In short, Your Answer would be Option A

Hope this helps!

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
