Work Step by Step
First, solve for y with both lines: y = 2x - 6 (already solved for y) and -4x = 2y -2x=y The slope of the form y =mx+b is always m, so in the line y=2x-6, we have slope 2. Similarly, the slope of the second line is -2. Since both slopes are not the same, they are not parallel. Since one slope is not the negative reciprocal of the other (1/2), the answer has to be neither.
