If you ae talking about the graph of a straight line that is a linear equation to find that equation u just need to take any 2 points of that line n put into following formula to get tha equation of that line

Let points are (x1,y1) and (x2, y2)

equation of the line is    ( y - y1)/(x - x1) = (y2 - y1) /( x2 - x1)
