Question

Are the graphs of the equations parallel, perpendicular, or neither? =+y equals 4 x plus 1 and =−−y equals negative 4 x minus 2

Answer 1

Answer: Neither parallel, nor perpendicular

Explanation:

The given equations are

y = 4x+1

y = -4x-2

Each equation is in y = mx+b form with m as the slope.

The slopes 4 and -4 are not equal, so the lines aren't parallel.

The slopes do not multiply to -1, so the lines aren't perpendicular either.
