1. QuestionMultiple choice

A function has values x: 1, 2, 3 and y: 4, 7, 10. Which rule represents the function?

Please select an answer first.

Correct answer: A

The correct answer is y equals 3x plus 1.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: Each increase of 1 in x increases y by 3, and 3 times 1 plus 1 equals 4.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

Each increase of 1 in x increases y by 3, and 3 times 1 plus 1 equals 4.

2. QuestionMultiple choice

A proportional relationship follows y equals 2.5x. What is y when x equals 8?

Please select an answer first.

Correct answer: B

The correct answer is 15.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: Substitute 8: 2.5 times 8 equals 20.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

Substitute 8: 2.5 times 8 equals 20.

3. QuestionMultiple choice

What is the slope of the line through (1, 2) and (4, 8)?

Please select an answer first.

Correct answer: C

The correct answer is 1.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: Slope equals change in y divided by change in x: 6 divided by 3 equals 2.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

Slope equals change in y divided by change in x: 6 divided by 3 equals 2.

4. QuestionMultiple choice

What is the y-intercept of y equals negative 2x plus 5?

Please select an answer first.

Correct answer: D

The correct answer is Negative 2.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: In slope-intercept form y equals mx plus b, b is the y-intercept, so it is 5.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

In slope-intercept form y equals mx plus b, b is the y-intercept, so it is 5.

5. QuestionMultiple choice

A function follows f of x equals 4x minus 1. What is f of 6?

Please select an answer first.

Correct answer: A

The correct answer is 23.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: Substitute 6: 4 times 6 minus 1 equals 23.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

Substitute 6: 4 times 6 minus 1 equals 23.

6. QuestionMultiple choice

A cyclist travels 180 kilometers in 3 hours at a constant rate. What is the rate?

Please select an answer first.

Correct answer: B

The correct answer is 30 kilometers per hour.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: Divide 180 kilometers by 3 hours to get 60 kilometers per hour.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

Divide 180 kilometers by 3 hours to get 60 kilometers per hour.

7. QuestionMultiple choice

Which equation represents a line with slope 4 and y-intercept negative 3?
