Understanding the Coordinate Plane

What is the primary purpose of graphing in mathematics?

• To make math problems more complicated

• To turn mathematical relationships into visual representations

• To replace numbers with symbols

• To solve equations without calculations

What is the coordinate plane primarily composed of?

• A single number line

• Two parallel number lines

• Two perpendicular number lines intersecting at their zero points

• A grid of random numbers

What are the two numbers used to specify the location of a point on a coordinate plane called?

• Variables

• Integers

• Coordinates

• Dimensions

What are the standard variable names for the horizontal and vertical axes on a coordinate plane, respectively?

• A-axis and B-axis

• Horizontal-axis and Vertical-axis

• X-axis and Y-axis

• Length-axis and Width-axis

When plotting a point (x, y) on a coordinate plane, what is the first step to locate the x-value?

• Draw a horizontal line through the x-value on the y-axis.

• Draw a vertical line through the x-value on the x-axis.

• Move horizontally from the origin to the x-value.

• Move vertically from the origin to the x-value.

What does the intersection of the vertical line representing the x-value and the horizontal line representing the y-value indicate?

• The origin of the coordinate plane.

• The exact location of the plotted point.

• The slope of the line connecting the axes.

• The area of the quadrant.

To plot the point (3, -2) starting from the origin (0,0), what movements should you make?

• Move 3 units left, then 2 units up.

• Move 3 units right, then 2 units up.

• Move 3 units right, then 2 units down.

• Move 3 units left, then 2 units down.

In which quadrant are both the x-value and the y-value negative?

• Quadrant 1

• Quadrant 2

• Quadrant 3

• Quadrant 4
