Step-by-step explanation:
Well, if you want to graph it you have to do it like this. for the x-axis you do,
(the 0 makes it turn to nothing)
x-axis
4x-2y(0)=10
4x=10
4x/4=10/4
x=2.5
y-axis
4x(0)-2y=10
-2y=10
-2y/-2=10/-2
y= -5
(2.5,-5)
(Make a straight line from both points so they connect)
Hope this helps! :D
