How do you change a equation into y equals mx plus b form?

Answer 1

One way to do this is to isolate the y-value. If you had, for instance the equation 2x + 3y = 12, then you would subtract 2x from both sides and divide by 3 to obtain y = 4 - 2/3x. You could then switch the order to get y = -2/3x + 4, the exact form you need. In some cases, though, this method is difficult or unnecessary. In those instances, it is best to remember that m is the rate at which the equation rises, or the slope, and b is the point at which the function crosses the y-axis. Often, it is very easy to isolate these parts of an equation no matter what form it is in. If you know these factors, then, you can plug them into their appropriate positions, and adjusting the variables from there is simple.
