WebTo equation, unknown = -1/2 x - 1 has a fraction as the coefficient of x. This becomes a little trickier in choosing x coordinates because we could end up with a fraction by the y coordinate. Those then becomes a little more difficult to graph. So, the gimmick is to look at of denominator of the coefficient. WebLet’s graph the equation y = 2 x + 1 y = 2 x + 1 by plotting points. We start by finding three points that are solutions to the equation. We can choose any value for x x or y, y, and …
