Question

draw the graph of the following equation on the same graph sheet x - y =0 , x + y = 0 , y + 5 = 0 also find the area enclosed between these lines

Answer 1

keep any value of x or y
Like 1,2,-1,0......
and find 3 solutions for each equation like
x-y=0
When x= 5
y is also 0

x=9 y=9

x=-1 y=-1

Find solutions of each eq

and plot them on graph

x axis y axis.......



then acknowledge the area between them and count the number of blocks....

this is your area
