Question
For the linear equation, given above, draw the graph and then use the graph drawn $($in the following case$)$ to find the area of a triangle enclosed by the graph and the co$-$ordinates axes$:7 - 3 (1 - y) = - 5 + 2x.$

Answer
First draw the graph as follows:
This is a right triangle.
Thus the area of the triangle will be:
$A=\frac{1}{2} \times$ base $\times$ altitude
$=\frac{1}{2} \times \frac{9}{2} \times 3$
=$\frac{27}{4}$
$=6.75\ sq.units$
This is a right triangle.
Thus the area of the triangle will be:
$A=\frac{1}{2} \times$ base $\times$ altitude
$=\frac{1}{2} \times \frac{9}{2} \times 3$
=$\frac{27}{4}$
$=6.75\ sq.units$
