Slope-Intercept Form
From our graphing of linear equations, we know that an equation written in Slope-Intercept Form looks like y = mx + b. When an equation is in this form, m = the slope of the line and b = the y-intercept of the line.
If you know the slope and the y-intercept of the line, you can easily put those values in to an equation in slope-intercept form. For example, if the slope is 2 and the y-intercept is -5, substituting 2 for m and -5 for b will give you y = (2)x + (- 5) which simplifies to y = 2x - 5.
