2-4 additional practice parallel and perpendicular linesdetermine whether this is parallel, perpendicular, or niether. y=3x+5-3x-y=9y-7x=314x-2y=28

The first pair of lines is neither perpendicular not parallel. The second pair of lines is parallel.

Step-by-step explanation:

If a line is defined as

Therefore the slope of the line is

Slope of parallel lines are equal. Product of slopes of perpendicular lines is -1.

In the first pair of lines,

It is a slope intercept form of a line, therefore the slope of the line is 3.

This equation can be written as

Slope of the line is

The slopes of both lines are not equal therefore the lines are not parallel. The product of their slopes is not -1, therefore the lines are not perpendicular.

In the second pair of lines,

This equation can be written as

Therefore the slope of the line is

This equation can be written as

Since the slopes of lines are equal, therefore the lines are parallel to each other.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

answer: what statements

step-by-step explanation if you write the statements down then i could you.
