Question

What is the y-intercept of the function f(x)=4 - 5x? -5 -4 4 5

Answer 1

Answer:

c

Step-by-step explanation:

Answer 2

Answer:

The y-intercept is 4. The third option is correct

Explanation:

The equation of a line is written as:

y=mx+b

Where m is the slope and m is the y-intercept or the point where y crosses the x-axis.

The given function is f(x)=4-5x.

It can be rewritten as

f(x)=-5x+4.

We can recognize the slope m=-5 and the y-intercept b=4

First option: Incorrect. The y-intercept is not -5

Second option: Incorrect. The y-intercept is not -4

Third option: Correct. The y-intercept is 4

Fourth option: Incorrect. The y-intercept is not 5
