Question

Given the equations of two lines. Determine if the lines are parallel, perpendicular or neither y=1/2x+7 and y= 2x + 3

Answer 1

y=1/2x+7   slope = 1/2

y= 2x + 3  slope = 2

for the lines to be parallel the slopes have to be the same

for the lines to be perpendicular the lines have to be negative reciprocals (1/2 * 2) = -1  they are not

Answer:

they are neither

Answer 2

I believe this would be neither
