How do you know if a point is above or below a line?
2 Answers. If the line equation is y=ax+b and the coordinates of a point is (x0,y0) then compare y0 and ax0+b, for example if y0>ax0+b then the point is above the line, etc.
What is the formula for a line?
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.
