Straight Line Equations[edit]

Straight Line through 2 points[edit]

If there are 2 points (x1,y1) and (x,y) a line can be drawn these two points with a slope

The equation of the line can be

Straight Line through point[edit]

From above if x1 and y1 equal zero then

y = x

Equation of a straight line through point (0,0) that has a slope equal 1
