Part of an ordered pair matching the x-axis

• x-axis

• y-axis

• x-coordinate

• y-coordinate

Part of an ordered pair matching the y-axis

• x-axis

• y-axis

• x-coordinate

• y-coordinate

Pairs of numbers that indicate the position of a point on a coordinate grid

• ordered pair

• x-axis

• y-axis

• solution

In an ordered pair the second number represents which axis?

• x

• y

How many points (ordered pairs) are on 1 line?

• 1

• 2

• 100

• infinite

How can you check to see if a point (an ordered pair), lies on a line?

• Graph it and check.

• Guess.

• Substitute the x and y-coordinates into the equation of the line to see if they make the equation true.

• Any ordered pair can be found on any line.

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 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 coordiate grid, is it possible these 2 lines only intersect once?

• yes

• no
