A straight line intersects the coordinate axes at a point individually The intersection point of the line with the {eq}x {/eq}axis is called the {eq}x {/eq}interceptThe graph of a linear equation is a straight line To locate that straight line you just need two points To find a point, you give a value to one of the variables (x or y),We see that all those solutions lie on a straight line In fact, every pair (x, y) that solves that equation will be the coördinates of a point on that line On that line, every coördinate pair is (x, 2x 1) y = 2x 1 That line, therefore, is called the graph of the equation y = 2x 1 And y = 2x 1 is called the equation of that line
