Question

In the function above, the slope will be multiplied by -4, and the y-value of the y-intercept will be decreased by 1 unit. Which of the following graphs best represents the new function?

A. Y
B. X
C. W
D. Z

Answer 1

In the function above, the slope will be multiplied by -4, and the y-value of the y-intercept will be decreased by 1 unit. Which of the following graphs best represents the new function?

A. Y

Answer 2

The correct answer is option D. Z.

Explanation:

• The graph which best represents the new function is Graph Z.
• As, if (a, b) is a point in the graph of f(x), then (a, b + d) is a point in the graph of f(x) + d.
• Linear functions are the algebraic equations whose graphs are straight lines and have unique values for their slope and y-intercepts.
• So, the graph which best describes the new function is graph Z.
