Please help me! x-2y=3 How the heck do I graph this? heck, how the heck do I solve it?!
Add 2y to both sides
subtract 3 from both sides:
Divide both sides by 2:
This is now in the form of a typical straight line... can you derive the gradient and y-intercept from here?
Also, what do you mean by "solve" it? This is 1 equation in 2 unknowns, hence you cannot solve.
One way to do that is to find the "intercepts". If y= 0 then x= 3 so (3, 0) is on the graph. If x= 0, then -2y= 3 or y= -3/2 so (0, -3/2) is on the graph. Draw the line between those two points.
