Question 354201: Hi
Can you help me?
I cant figure this out:
How do you graph these equations by using the x and y intercepts?
x-y=3
10x=-5y
4x=2y+6
Thank you!!

You can put this solution on YOUR website!
Where the line crosses the x axis, x = 0 and where it crossed the y axis y = 0
so solve each equation using first x = 0 then again with y = 0,.
x-y = 3 if x = 0
0-y = 3
-y = 3
y = -3 so the x intercept is (0, -3)
x-y = 3 if y = 0
x - 0 = 3
x = 3 so the y intercept is (3, 0)
Now graph each point and connect them with a line..you only need two points to graph a linear system.
Do the same to the other two equations
Hope this helps
