Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

y = (-1/4 )x + 8

–2x + 8y = 4

a. parallel

b. perpendicular

c. neither

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 :)

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
