Lines Thru Origin Using Intercepts
The minimum number of points needed to graph a line is two points. This presents a small problem if a linear equation has both its x and y intercepts at the origin (which would be the same point). If this rare situation happens, simply find one other point on the line by plugging in any value of x and find it’s corresponding y-value. Then you will have two points on the line, and can connect the dots to graph the linear equation.
