A function is represented by the equation y = 7x + 4. Which of the following statements are true? (Select all that apply.)

Select an answer

A.
Its slope is 4.


B.
It has a positive slope.


C.
Its y-intercept is 7.


D.
It represents a linear function.

Answer 1

Correct answers: B and D.

- Slope = 7, which is positive, so B is true (A is false).
- y-intercept = 4 (not 7), so C is false.
- y = 7x + 4 is a linear function, so D is true.
