Question

are these lines parallel perpendicular or neither y=2x+7 and y=-2x+5

Answer 1

Parallel and perpendicular lines

Line equation

We know line equation is given by

y = mx + b

The number m is called the slope of the line and it shows the inclination of the line

Parallel lines

Two lines are parallel when they have the same inclination

For the first line m = 2 and for the second m = -2

Then they are not parallel

Perpendicular lines
