Understanding Parallel Lines and Slopes

What is the defining characteristic of parallel lines?

• They intersect at one point.

• They have different slopes.

• They do not intersect.

• They are on different planes.

How do you calculate the slope of a line?

• By dividing the change in y by the change in x.

• By multiplying the change in y by the change in x.

• By adding the change in y and the change in x.

• By dividing the change in x by the change in y.

What is the slope of line A?

• 1/2

• 4/6

• 2/4

• 3/5

Why are lines A and B considered parallel?

• They have the same slope.

• They are on different planes.

• They intersect at one point.

• They have different slopes.

Why is line C not parallel to lines A and B?

• It intersects with A and B.

• It has the same slope as A and B.

• It is on a different plane.

• It has a different slope.
