Graphing linear equations with 3 variables
WebThis involves a variation on substitution that will not likely be taught in your class, but I find much easier to work with. Take the two equations that contain z and solve for z. 3x+5y … WebGraph the line y = 3 x + 1 . From the equation, we know that the y -intercept is 1 , the point ( 0, 1) and the slope is 3 . Graph the point ( 0, 1) and from there go up 3 units and to the right 1 unit and graph a second point. Draw the line that contains both points. Horizontal and vertical lines have extra simple equations.
