Question

draw the graph on the following equationon the same graph sheet: x=4,x+5=0,y=2,y-1=0 also find the area enclosed between these lines.

Answer 1

By drawing graph we will get rectangle shape so,the area of rectangle is LXB 
L=3
B=9
The area=27units

Answer 2

area of the shaded region = (4-(-5))*(2-1)
                                           = 9*1
                                           = 9 sq units
