Question

Solve the system of equations graphically and check solutions algebraically.
How do I start, help!?
x+2y=7
3x+y=6

Answer 1

You would need to graph the two points and find where they intersect (the x and y coordinates)
Algebraically:
(x + 2y = 7)*1 to x+2y = 7
(3x + y = 6)*2 to 6x +2y = 12
5x = 5 (Subtract the two equations)
x = 1 y = 3

Answer 2

How do you graph that?

Answer 3

Punch it into a grapher (calculator or online)

Answer 4

I know how to get to the solution by doing what you did, but how do I solve the system of equations graphically...I don't understand how to punch it in...
