8x-4y=16
8x+4y=16
solving systems of equations graphically
---------------
To graph them:
They're straight lines, so you need points for each.
8x-4y=16 --> y = 2x - 4
Pick 2 values for x and find y
eg,
x = 0, y = -4 --> the point (0,-4)
x = 2, y = 0 ---> the point (2,0)
Plot the 2 points, draw a line thru them.
=================
Do the same for the other equation.
The intersection is the solution of the system.
