Question

4x+y=1

Answer 1

It's a linear equation. Not sure what you are asking. What are you asked to do? Graph it?

If graphing, I would probably use the intercepts.

Plug in x=0 and solve for y; that gives you the y-intercept, so plot that point on the y-axis. Plug in y=0 and solve for x. That gives you the x-intercept, so plot that point on the x-axis. Connect the dots, there's your line.

If the question is something else, you'll need to elaborate.
