What is the y-intercept
7x-4y=-28

Thus, the y-intercept of the line is 7

Step-by-step explanation:

One given line can be expressed with the slope-intercept form as follows:

Where m is the slope of the line and b is the y-intercept.

We are given the following equation of the line:

7x-4y=-28

Let's transform the equation to look like the slope-intercept form [1].

Subtract 7x:

-4y=-7x-28

Divide by -4:

y=7/4x+7

Comparing with the equation [1]:

m=7/4

b=7

Thus, the y-intercept of the line is 7

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
