Hey there! I'm happy to help!
Here's how to find the slope given any two points.
Subtract the y values.
14-(-18+-14+18=32
Subtract the x values.
-6-2=-8
And divide those.
32/-8=-4
The slope is -4.
Have a wonderful day! :D
For the given table, the difference between two consecutive y terms are

It means the difference is constant. So the given function is in arithmetic progression.
And to find the equation, representing the given series, we will use the formula for the nth term of arithmetic series, which is

Here,

So we will get

3) Multiply the price of the item ($40) by the percent of the sales tax (8%). Then add that to the price of the item to get the total.
=$40 * 8%
=40 * 0.08
=$3.20 tax
=$40 price of item + $3.20 tax
=$43.20 total
5) Multiply the number of students in the band last year (36) by the percentage increased (125%).
=36 * 125%
=36 * 1.25
=45
Hope this helps! :)
