Step 1: Construct a table of values for given line equations

NOTE: Select some values of x and then evaluate those values in the given

equation to get the corresponding values of y.

EXAMPLE: 2x + 3y = 12

x = 0 3 6....

y = 4 2 0.....

Do this for remaining equation for x and y coordinates

Step 2: Plot those points in the xy-axis, and connect them with a straight edge.

NOTE: x = 0 means y- axis and y =0 means x-axis

Step 3: From the figure, notice the base and altitude of the triangle

EXAMPLE: From the figure, notice that the base of the triangle = 5 units

Altitude = 2 units

Step 4: Substitute in the area formula of the triangle

NOTE: \frac{1}{2} base * height

EXAMPLE:   \frac{1}{2} (5 *2

Area = 5
