Coordinate Grid Parallel Lines

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.

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 are on 1 graph, is it possible they never intersect?

• yes

• no

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 are graphed on 1 coordinate grid, which of the following are possible:

• The 2 lines intersect once.

• 2 lines cannot be graphed on 1 coordinate grid.

• The 2 lines share all of their points.

• The 2 lines never intersect.

Which of the following is NOT a characteristic of the coordinate plane?

• It has two parallel number lines.

• The x-coordinate determines horizontal movement.

• The y-coordinate determines vertical movement.

• The origin is at (0,0).
