Q11 of 58 Page 44

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.

0.y + 1.x = 4


Y could be anything because coefficient of y is zero. X has to be 4.



Similarly for y = 3



3x + 4y = 12




As we can see here The Triangle is Right angle triangle So we need base and Height.


Base = 4 units, Height = 3 units


Area =


Area = 6 unit2
