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

The  y-intercept of f(x) = 4 - 5x is 4.

Using the slope intercept formula the  y-intercept can be found below

where

m = slope

b = y-intercept

From the equation:

f(x) = 4 - 5x

According to the slope intercept format,

m = slope = -5

y- intercept = 4

Therefore, the  y-intercept of f(x) = 4 - 5x is 4.

y-intercept = (0,4)

Step-by-step explanation:

To find the y-intercept, the place at which the value of x is 0, simply plug zero into your function:

f(x) = 4 - 5x

f(0) = 4 - 5(0)

f(0) = 4

Hence, the y-intercept occurs at (0,4).

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
