Question

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

Answer 1

A

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 =
`(4)/(3)` x + 2 → has slope m =
`(4)/(3)`

y = -
`(3)/(4)` x - 7 → has slope m = -
`(3)/(4)`

and
`(4)/(3)` × -
`(3)/(4)` = - 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
