The slope-intercept form of a line is the way you will see most lines expressed in algebra. The form is y=mx + b where m=the slope and b= the y-intercept. For example the line y=3x + 7 has a slope =3 and a y-intercept=7. When graphing lines in slope-intercept form you need to follow two steps. First plot the y-intercept on the y-axis that will location is the first point on the line. Next from that point use the slope as driving directions to find a second point. The notes below will help you sharpen this most critical algebra skill.
