Question

What is the y-intercept of the function f(2)=4-5x?-5-445​

Answer 1

C. 4

First, rearrange the equation into slope intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. You get y = -5x + 4. This means the y-intercept is 4.

Answer 2

For this case we have a function of the form $y = f (x)$

Where:

$f (x) = 4-5x$

To find the y-intercept of the function we must do x = 0.

Then, replacing:

$f (0) = 4-5 (0)\\f (0) = 4-0\\f (0) = 4$

So, the y-intercep of the function is 4
