Graphing points

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). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What does the first number in a coordinate pair represent?

Back

The first number in a coordinate pair represents the horizontal position of the point on the x-axis.

Front

What does the second number in a coordinate pair represent?

Back

The second number in a coordinate pair represents the vertical position of the point on the y-axis.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you plot the point (3, 4) on a coordinate plane?

Back

Start at the origin (0, 0), move 3 units to the right (positive x-direction), and then move 4 units up (positive y-direction).

Front

What is the difference between positive and negative coordinates?

Back

Positive coordinates are located in the first quadrant (top right) and the fourth quadrant (bottom right), while negative coordinates are located in the second quadrant (top left) and the third quadrant (bottom left).

Front

What is the significance of the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the significance of the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

How do you identify a point in the second quadrant?

Back

A point in the second quadrant has a negative x-coordinate and a positive y-coordinate.

Front

What does it mean for points to be 'not like the rest'?

Back

It means that one point has a different characteristic (e.g., location, sign of coordinates) compared to the others.
