WebEquation for a Line. Think back to algebra and the equation for a line: y = mx + b. In the equation for a line, Y = the vertical value. M = slope (rise/run). X = the horizontal value. B = the value of Y when X = 0 (i.e., y-intercept). So, if the slope is 3, then as X increases by 1, Y increases by 1 X 3 = 3. Conversely, if the slope is -3, then ...
