When graphing data, we use two intersecting number lines called axes. Together these axes create what we call the coordinate plane.

Which variable represents the horizontal (left-right) axis?

Interactive popup. Assistance may be required.
The horizontal axis is represented by the *x*.

Which variable represents the vertical (up-down) axis?

Interactive popup. Assistance may be required.
The vertical axis is represented by *y*.

How would you graph the point *x* = -3 on a single number line?

Interactive popup. Assistance may be required.
Place a dot on the number line at -3.

How would you plot the point *y* = 2 on a single number line?

Interactive popup. Assistance may be required.
Place a dot on the number line at 2.

If each axis represents a number line, how would you graph an (*x*, *y*) point like (-3, 2)?

Interactive popup. Assistance may be required.

Place a dot on the grid that lines up with -3 to the right and 2 up.
