Khan Academy and Coordinate Plane Quiz

What is the x-coordinate in the ordered pair (6, -8)?

• 6

• 0

• 8

• -8

Answer explanation

In the ordered pair (6, -8), the first number represents the x-coordinate. Therefore, the x-coordinate is 6, making it the correct answer.

Which axis is horizontal on the coordinate plane?

• Y-axis

• Z-axis

• X-axis

• W-axis

Answer explanation

The X-axis is the horizontal axis on the coordinate plane, while the Y-axis is vertical. The Z-axis and W-axis are used in higher dimensions, but for a standard 2D plane, the correct answer is the X-axis.

In which quadrant is the point (6, -8) located?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Answer explanation

The point (6, -8) has a positive x-coordinate and a negative y-coordinate. This places it in Quadrant IV, where x is positive and y is negative.

What is the y-coordinate in the ordered pair (6, -8)?

• 6

• -8

• 0

• 8

Answer explanation

In the ordered pair (6, -8), the first number represents the x-coordinate and the second number represents the y-coordinate. Therefore, the y-coordinate is -8, making it the correct answer.

What is the origin in a coordinate plane?

• (1, 0)

• (0, 1)

• (0, 0)

• (1, 1)

Answer explanation

The origin in a coordinate plane is the point where the x-axis and y-axis intersect, which is represented by the coordinates (0, 0). This is the starting point for measuring all other points.

What is the first step in plotting the point (6, -8)?

• Move 8 steps up

• Move 6 steps left

• Move 6 steps right

• Move 8 steps down

Answer explanation

To plot the point (6, -8), start at the origin (0, 0). Move 6 steps to the right along the x-axis to reach (6, 0). Then, you would move down, but the first step is moving right.

What is the second step in plotting the point (6, -8)?

• Move 8 steps up

• Move 6 steps left

• Move 6 steps right

• Move 8 steps down

Answer explanation

To plot the point (6, -8), start at the origin (0,0). First, move 6 steps right to reach (6,0). Then, since the y-coordinate is -8, move 8 steps down to reach (6,-8). Thus, the second step is to move 8 steps down.

What is an ordered pair?

• A pair of numbers representing a point on the coordinate plane

• A pair of letters representing a point on the coordinate plane

• A pair of shapes representing a point on the coordinate plane

• A pair of colors representing a point on the coordinate plane

Answer explanation

An ordered pair consists of two numbers, typically written as (x, y), which represent a specific point on the coordinate plane. This makes the first answer choice correct, as it accurately describes the concept.
