Here are the points you can use to make you’re line graph :
(0, 7)
(1, 5)
(2, 3)
(3, 1)
Just connect these points and you’ll have your line. :)
I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
4 Tickets to alaska will cost 3832$. 4 Tickets to Vancouver however will cost 2938$. 3832$ - 2938$ = 894$. They will save 894$
First we have to find how much they spent on each gallon.
To find out how much Carly paid for each gallon we have to divide her total price by haw many gallons she got.
$17.50/7=$2.50 per gallon
Likewise we do the same for Jade
$45/15=$3
So the answer will be Jade paid more per gallon than Carly
