A. –4y = –6x + 8
y=3/2x2
B. –4x + 5y = 8
5y = –4x + 6
C. –2x + 4y = 3
y= 1/2x+6

A. When you multiply the second equation by 4, it'll be identical to the first one.

they are linear. so to have infinite solutions, they would have to be equivalent expressions.

so checking A \[4y=6x+8\]\[4y=6x8\]\[y=\frac{6}{4}x\frac{8}{4}\]\[y=\frac{3}{2}x2\]

which is the same as the second equation, therefore there are infinite number solutions to this system of equations.
