Let us draw the graph of the equation From the graph let’s determine the value of y where x = –2 and the value of x where y = 3.

Let us draw the graph of the equation and calculate the area of the triangle formed by the graph and the axes and write the area.

Let us draw the graph of the three equations x = 4, y = 3 and 3x + 4y = 12 and determine the area of the triangle formed by the graph.

Let us solve graphically:

The graph of the equation 2x + 3 = 0 is
