Yes, both ways are the same. The way the other person told you is in what is called y-intercept form, and the form that you have it in right now (4x - y = 7, I think it was) is called standard form. Basically, just by adding and subtracting things to move

All you have to do is try out some numbers. An easy way is to place 0 in for x and y to find some easy x and y-intercept points. Just plug in 0 for x. 4 times 0 is obviously 0, so 0 minus what equals 7? 7. Do the same for y. Hope I helped! :-)
