Alyssa wants to know the gas mileage of her new car. She kept track of the number of miles she traveled and the number of gallons she used. Which method and reasoning can Alyssa use to calculate the gas mileage in miles per gallon?

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

not sure but it may be b, as i said i'm not sure.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

wait this depends wether emily and zach how they are thinking.

yes they are the same.
