The expressions we need to do subtraction with :

Let us now subtract those expression by combining like terms and simplifying them until they can no longer be simplified :

Therefore, the answer to :

unless if u could do my questions, if not i wouldn't want to

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
