y=|x|-5
3x-1=6x+y
so confused. please help.
Well, then, there is no way to "solve" these equations because there are two variables (x and y). But we CAN graph them.
If you look at my last post, you'll see that I "broke up" the first equation into two seperate equations. If you sketch the graph, it'll look like a v.
Solve for y:
You can see that this is a linear equation of the form , where is the slope of the line, and is the y-intercept.
You can use the y-intercept along with the slope of the line to sketch the graph. Or you could use the y-intercept along with another point (ie (1,-4)) to draw the graph. Either way is fine.
