Question

5. For each linear equation, given above, draw the graph and then use the graph drawn (in each case) to find the area of a triangle enclosed by the graph and the co-ordinate axes : 3x-(5-y)=7​

Answer 1

Answer:

The correct Answer is 24 sq. unit

Answer 2

Given equation is 3x−(5−y)=7.

3x+y=12

Here x intercept is 4 and y intercept is 12

The required triangle formed will be right triangle having base and height equal to 4 and 12 respectively.

Area of the right triangle obtained will be:
