Question

Using the slope, state whether the lines are parallel, perpendicular, or neither.

Y= 2x-3
y=-1/2x+2

Answer 1

Parralel lines have the exact same slope.

in the equation y=mx+b m is the slope

Both of these equations are in slope intercept form (y=mx+b) meaning that the coefficient in both equations is the slope.

Parralel lines have the same slope and perpendicular lines have the inverse opposite slope. For example if a line had a slope of 2 or 2/1 then the perpendicular line to it would have a slope of -1/2.

With that knowledge we can easily see that the lines are perpendicular since their slopes (represented by the coefficient) are the inverse opposite.

Perpendicular is your answer
