Question

Mike and his bestfriend dan have the same birthday, but mike is three years older than dan. Let the variable x represent mikes age and y represent dans age. Which graph represents the relationship between Dans age and Mikes age ?

Answer 1

x=Mike's age

y=Dan's age

It is given that,Mike is three years older than dan.

→ x=y+3

If you will draw the graph of the function, it will cut x axis at (3,0) and y axis at (0,-3).

⇒Graph-2

Answer 2

X= Mike
y= Dan

Mike is 3 years older than Dan
x-3=y
