Pics included. Please help, will give medal.

Answer 1

i know it is b

Answer 2

But what is the solution set?

Answer 3

To solve a system of equations graphically, graph both equations and see where they intersect. The intersection point is the solution. The slope intercept method of graphing was used in this example. The point of intersection of the two lines, is the solution to the system of equations

Answer 4

So would it be b? and if so what is the solution set? and how do i graph it?

Answer 5

to solve it do\[7x-4y=3\]and\[21x-12y=9\]

Answer 6

Okay so it is a. (8,0)?

Answer 7

somewhere over here

Answer 8

yes

Answer 9

and the x and y intercepts so i can graph it myself?
