These questions are from millions of online tutorials and YouTube websites. I don’t know if I am allowed to ask experts to explain those questions in a different way. They are not homework assignments. I am trying to develop my own web site. Math’s has many ways to solve the problems. Just want to understand them.

1. My question is why the answer is not -4

As this equation has two variables, any solution of one variable will be another formula with factors rearranged...

The standard "line" formula is "y = mx + b"  
This is called the "slope-intercept" form and expresses the value y in terms of the "slope"  (m in that equation)
and the "y intercept" (b in that equation)...

The y intercept is calculated by setting x to 0 as shown...

You can draw this standard graph by plotting the two intercept points:
x intercept:  (7,0)
y intercept:  (0, -4)
and drawing a straight line connecting them...

Not sure what additional explanations you need?

Thanks for this detailed information.  The answer -4 is incorrect but the answer 4/7x -4 is correct. I thought -4 would be a correct answer.
