Hey guy's :) I need some help again come take a look please?

John began his job making $20 the first day. After that he was paid $6.00 per hour. Y = 6x + 20. Using the graph you drew for the equation, predict the pay for John if he works 7 hours after the first day.

From my previous post of drawing linear line,
Find x = 7 ( 7 hrs) => y = the pay!
Double check  y = f (7) = 6 * 7 + 20 = $62

It's  given John gets $20 + 6 per hour
Let Y be the total earnings 
x= no. of hours worked
$$Y=6x+20$$
it's given he works 7 hours, so x=7
We get
$$Y=6 \times 7+20=$62$$
We can also find this from the graph of the line
Let's plot it , we need two points 
put x=0, we get y=20
so one point is (0, 20)
let's put y=0
so we get x=-20/6=-3.333
so other point is (-3.33, 0)
|dw:1333513162362:dw|
from the graph also we see y=$62
