Coordinate Geometry Practice Tests

These Grade 9 Math practice tests cover the coordinate plane, quadrants, axes, ordered pairs, distance, midpoint, slope, equations of lines, intercepts, parallel and perpendicular lines, reflections, rotations, translations, dilations, and coordinate-plane geometry applications.

Skills covered

  • Locating points and identifying quadrants, axes, and the origin
  • Finding distance, midpoint, slope, intercepts, and equations of lines
  • Recognizing parallel and perpendicular relationships
  • Applying translations, reflections, rotations, dilations, and scale factors
  • Using coordinates to solve perimeter, area, triangle, rectangle, and rate problems

How to use these practice tests

Read each ordered pair as (x, y), preserve positive and negative signs, choose the appropriate coordinate formula, and check the result on a graph or in the original geometric context.

1. QuestionMultiple choice

In which quadrant is the point (3, 4)?

Please select an answer first.

Correct answer: A

The correct answer is Quadrant I.

  1. Identify the coordinate information: Determine the points, quadrant, slope, distance, midpoint, transformation, or geometric model involved.
  2. Apply the coordinate rule: Both coordinates are positive, so the point is in Quadrant I.
  3. Check the position or measurement: The correct choice is Quadrant I.

Both coordinates are positive, so the point is in Quadrant I.

2. QuestionMultiple choice

In which quadrant is the point (-2, 5)?

Please select an answer first.

Correct answer: B

The correct answer is Quadrant II.

  1. Identify the coordinate information: Determine the points, quadrant, slope, distance, midpoint, transformation, or geometric model involved.
  2. Apply the coordinate rule: The x-coordinate is negative and the y-coordinate is positive, so the point is in Quadrant II.
  3. Check the position or measurement: The correct choice is Quadrant II.

The x-coordinate is negative and the y-coordinate is positive, so the point is in Quadrant II.

3. QuestionMultiple choice

In which quadrant is the point (-4, -1)?

Please select an answer first.

Correct answer: C

The correct answer is Quadrant III.

  1. Identify the coordinate information: Determine the points, quadrant, slope, distance, midpoint, transformation, or geometric model involved.
  2. Apply the coordinate rule: Both coordinates are negative, so the point is in Quadrant III.
  3. Check the position or measurement: The correct choice is Quadrant III.

Both coordinates are negative, so the point is in Quadrant III.

4. QuestionMultiple choice

In which quadrant is the point (6, -3)?

Please select an answer first.

Correct answer: D

The correct answer is Quadrant IV.

  1. Identify the coordinate information: Determine the points, quadrant, slope, distance, midpoint, transformation, or geometric model involved.
  2. Apply the coordinate rule: The x-coordinate is positive and the y-coordinate is negative, so the point is in Quadrant IV.
  3. Check the position or measurement: The correct choice is Quadrant IV.

The x-coordinate is positive and the y-coordinate is negative, so the point is in Quadrant IV.

5. QuestionMultiple choice
