draw a graph of y= x

Answer 1

let y=1 then x=1
y=2 ;x=2
y=3 ;x =3

Given equation is y=∣x∣

⟹y={

x,

−x,

x≥0

x<0

For x≥0,plot the graph of y=x

we need atleast two points on y=x for which x≥0

For x=0 ,y=0

for x=1,y=1

(0,0) and (1,1) are the solutions of y=x,x≥0

For x<0,plot the graph of y=−x

we need atleast two points on y=−x for which x<0

For x=−1 ,y=−(−1)=1

for x=−2,y=−(−2)=2

(−1,1) and (−2,2) are the solutions of y=−x,x<0
