The line y = 7 would just be a Horizontal line on 7
Basically, you go up 7 units then draw a straight horizontal line across

As Louis is only leaving a 20% tip on the pretax bill, this means he's leaving 20% of $27.62
The best thing to do is to find 10% and double it.
27.62/10= 2.76 (as it rounds down)
2.76*2= 5.52
Therefore, you've got to add $5.52 to $27.62
$5.52+$27.62= $33.14
Hope this helps :)
2x+3y is the expression simplified
