You can put this solution on YOUR website! determine if the equation is linear, if so, graph the function
2x+y=4
--------------
All exponents are 1 --> linear
==============
Pick 2 values for x and find y, plot the 2 points, draw a line thru them.
=============
Or,
Pick 3 values for x and find y, plot the 3 points.
If a straight line passes thru them, they're colinear, and it's linear.
