Plotting Points

What does the y-axis represent on a coordinate plane?

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

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

• The y-axis represents the distance from the origin to the right.

• The y-axis indicates the slope of a line on the coordinate plane.

If a point is located at (5, 0), what axis is it on?

• x-axis

• y-axis

• z-axis

• origin

If a point has coordinates (4, -2), where is it located?

• It is located 4 units to the right of the origin and 2 units down.

• It is located 4 units to the left of the origin and 2 units up.

• It is located 2 units to the right of the origin and 4 units down.

• It is located at the origin.

How would you plot the point (-3, 4)?

• Start at the origin, move left 3 units (x-coordinate), then move up 4 units (y-coordinate).

• Start at the origin, move right 3 units (x-coordinate), then move down 4 units (y-coordinate).

• Start at the origin, move left 4 units (x-coordinate), then move up 3 units (y-coordinate).

• Start at the origin, move right 4 units (x-coordinate), then move up 3 units (y-coordinate).

What is the relationship between the x-coordinate and the y-coordinate in an ordered pair?

• The x-coordinate indicates vertical position, while the y-coordinate indicates horizontal position.

• The x-coordinate indicates horizontal position, while the y-coordinate indicates vertical position.

• The x-coordinate represents the distance from the origin, while the y-coordinate represents the angle.

• The x-coordinate and y-coordinate are interchangeable and represent the same position.

What does it mean if a point is on the x-axis?

• Its y-coordinate is 0.

• Its x-coordinate is 0.

• It lies above the x-axis.

• It lies below the x-axis.

What does the x-axis represent on a coordinate plane?

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

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

• The line that represents the slope of a graph.

• The line that indicates the maximum value of y.

How do you identify the coordinates of a point on a graph?

• Locate the point, then read the x-coordinate from the x-axis and the y-coordinate from the y-axis.

• Estimate the coordinates based on the nearest grid lines.

• Use a ruler to measure the distance from the origin.

• Count the number of points to the right and up from the origin.

How do you plot the point (3, 5)?

• Start at the origin (0, 0), move right 3 units (x-coordinate), then move up 5 units (y-coordinate).

• Start at the origin (0, 0), move left 3 units (x-coordinate), then move down 5 units (y-coordinate).

• Start at the point (3, 0), then move up 5 units (y-coordinate).

• Start at the point (0, 5), then move right 3 units (x-coordinate).

What is the first number in an ordered pair called?

• x-coordinate

• y-coordinate

• origin

• point
