Recall / Warm-Up

1

Two lines are drawn so that they cross each other and form four right angles where they meet. What word describes these two lines?

2

A number line has tick marks at 0, 1, 2, 3, 4, and 5. Starting at 0, how many unit jumps does it take to reach the tick mark labeled 4?

3

If you switch the digits in the number 47 to get 74, do you end up with the same number?

Look at the coordinate grid. The horizontal line is called the   ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   -axis. The vertical line is called the   ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   -axis. The point where they cross is called the   ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   .

What is the ordered pair for the origin?

3

In the ordered pair (6, 2), the number 6 tells you how far to move along the   ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   -axis, and the number 2 tells you how far to move along the   ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   -axis.

Four points are plotted and labeled A, B, C, and D on the grid below. Which point is located at (5, 2)?

5

If you plot the point (0, 6), where does it lie?

6

A point is plotted on the grid below. Write its ordered pair: (  ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   ,   ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲   ).
