Just two points are needed to draw a straight line graph, although it is a good idea to do a check with another point once you have drawn the graph Example Draw the graph of \(y = 3x 1\)Thus, to graph an equation in two variables, we graph the set of ordered pairs that are solutions to the equation For example, we can find some solutions to the firstdegree equation y = x 2 by letting x equal 0, 3, 2, and 3 Then, for x = 0, y=02=2 for x = 0, y = 3 2 = 1 for x = 2, y =TITLE 'Average Monthly Rainfall in Olympic Cities';
