Answer 3

This is a school assignment, right?

Answer 4

Its a question for this lesson..... It has 8 other questions and i've done the most of the thing I just don't understand C E or F

Answer 8

This may be way late, but I'll show you what it should kind of look like:

Once you substitute the values for x into each equation, you should get two sets of data. Once plotted, the graphs should look something like this:



Essentionally, that graph is what C wanted you to show.

If you notice, at the point of intersection, both equations have the same value of y. Therefore, by setting both equations equal, you're saying that the point if intersection is where both equations have the same y value. Because both equations also intersect at the same x value, after equating both equations and solving for x, it will give you the value for x at which the intersection occurs. This essentially answers E.

F is answered by solving for x, and then substituting it back into one of the two equations to get y; you'll get the same value for y regardless of which equation you substitute it into. As a result, now you have a value for x and a value for y; this pair (x,y) is your point of intersection.

Sorry for the late response. Hopefully this is still a helpful response.
