Do the equations y = -6x +4 and y = 4x + 6 have one solution, no solution, or infinitely many solutions

Black_prince [1.1K]

Answer:

One solution

Step-by-step explanation:

We know there is only one solution because the lines do not have the same slope, nor are they the exact same line.

So we know they must have just one solution.

Best of luck
