Slope from Coordinate Pair or Graph

If 2 lines are graphed on 1 coordinate grid and never intersect, which of the following are true?

• They share all their points (ordered pairs).

• They don't have any common points (ordered pairs).

• They share one point (ordered pair).

• They have the same slope.

If 2 lines are graphed on 1 coordinate grid and cover each other completely, which of the following are true?

• They share all their points (ordered pairs).

• They intersect the origin.

• They share one point (ordered pair).

• They have the same slope.

If 2 lines on 1 coordiate grid are parallel and never intersect, how many points do they share? (Hint - sketch this and see)

• 0

• only 1

• at least 1

• 4

If 2 lines are graphed on 1 coordinate grid intersect once, which of the following are true?

• They share all their points (ordered pairs).

• They don't have any common points (ordered pairs).

• They share one point (ordered pair).

• They have the same slope.

What type of slope does the graph have?

• Zero

• Undefined

• Negative

• Positive

Find the slope:

• 2

• -2

• 1/2

• -1/2

These are two examples of slopes that are ______.

• reciprocals

• opposite reciprocals

• equal

• bisectors

find the slope

Example 1: one slope is 3 and the other slope is -1/3

Example 2: one slope is -4/3 and the other slope is 3/4

These are two examples of slopes that are ______.

• reciprocals

• opposite reciprocals

• equal

• bisectors

Slope represents...

• the steepness of a line/segment.

• the length of a segment.

• the half way point of a segment.
