What is the answer to this question I need help on this please?!

A

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

A

y = x + 2 → has slope m =

y = - x - 7 → has slope m = -

and × - = - 1

Thus this pair of lines are perpendicular

B are neither parallel nor perpendicular

C have equal slope and are parallel

D are neither parallel nor perpendicular

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
