Answer 1

Q.8 1.  

1. X+ 4 =0

SO X = -4

plot on the graph

y -1 =0

y= 1 ( plot on graph)

2x + 3= 0

2x =-3

x = 3/2

similarly the fourth one

and in question 9

x+ y = 2

take value of x as 0

then o + y =2

y = 2

plot on the graph

3x- y = 0

substitute  the value of x

similarly do the remaining problems
