What’s the answer cause I need it bad

Step-by-step explanation:

Given the following system of equations:

In order to solve the System of equations, you can use the Substitution method. The steps are:

1. You can solve for "x" from the second equation:

2. Substitute the equation obtained into the first original equation:

3. Now you must solve for "y":

4. Substitute the value of "y" into the equation and evaluate:

Then, the solution is:

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).
