How do you solve y4x-2 and y-x 3 by graphing? - Answers

There are equals missing from the equations, but that doesn't matter as you are asking how to solve by graphing:First, rearrange your equations into the form: y = mx + cYou can then plot on graph paper the two equations.In this case, they are both linear equations so the graphs will be a straight line. The easiest way to do this is to workout the y value for three chosen x values, eg x = -2, 0, 2, plot those points and draw the straight line that goes through all three. I suggest three points as it is always possible to draw a straight line through two points and as you know the line is straight, it acts as a check to ensure you have the right values.Once you have drawn both the lines, find the point of interception (when the lines cross) - if necessary extending the lines drawn - and read off the X and Y values from the graph.
