Graphing and Coordinate Plane

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (top right), Quadrant II (top left), Quadrant III (bottom left), and Quadrant IV (bottom right).

Front

What does the point (0,0) represent on a coordinate plane?

Back

The point (0,0) is called the origin, where the x-axis and y-axis intersect.

Front

How do you identify the quadrant of a point with positive x and negative y coordinates?

Back

A point with positive x and negative y coordinates is located in Quadrant IV.

Front

What is the formula to find the area of a rectangle on a coordinate plane?

Back

Area = length × width.

Front

If a point is reflected over the y-axis, how do its coordinates change?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What is the height of Lin's plant after 20 days if it grows 1.5 cm per day starting from 5 cm?

Back

The height will be 35 cm.

Front

What is the equation for total spending (s) based on the number of people (p) at a party if each person costs $15 and there is a $50 deposit?

Back

s = 15p + 50.

Front

In which quadrant is the point (-3, 12) located?

Back

Quadrant II.

Front

What is the distance between the points (2,3) and (2,7) on a coordinate plane?

Back

The distance is 4 units.
