To graph a Linear Equation in two variables in a form y = mx + b, plot the point (0, b) on a cartesian plane and determine the If the mis positive y-units from the point (0, b) and walk x-units to the right. If the m is negative y y-units from the point (0, b) and walk x-units to the right. This makes y, another point. Make a through this point and to point (0, b). X​
