Which equation, together with y = -1.5x + 3, makes a system with one solution?
A
y = -1.5x + 6
B.
y = -1.5x
C.
2y = -3x + 6
D.
2y + 3x = 6
E.
y = -2x + 3
we know that
If the system of a linear equations has only one solution, then both lines must to be different and the slope can not be equal
therefore
option A -----> same slope
option B-----> same slope
option C ----> same slope (m=-3/2=-1.5)
option D ---> same slope (m=-3/2=-1.5)
option E ----> different slope (m=-2)
therefore
