Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
2 answers:
The first equation is already solved, the slope is -1/4
The second equation you need to rearranged the numbers..
-2x+8y=4
8y=2x+4 now divide by 8
Y=4x+2
Which makes the answer perpendicular because they are both different signs and are swapped.
Hope this helps :)
