Answer:
zero
Step-by-step explanation:
The line is a horizontal line
Horizontal lines are of the form y= constant
This means they have zero slope
5-(-4)+2 should be the expression
so you should write 8 in a box then under the box write what place it is like hundredth and you do the same for the rest
8 0 7 , 8 2 5
hundred thousandth^ and so on^
The answer would be $120
that would make a grand total $1620
