To quickly sketch the graph of the solution set of a linear equation like $6x - 4y = 12,$ Vera described the following method. I find the coordinates of the x-intercept by mentally substituting O for y and then solve for x. To find the coordinates of the y-intercept, I substitute O for x and then solve for y. Then I draw the line through the two intercept points. Try Vera’s method for the equation $6x - 4y = 12$ and explain why it works.
