Assume that x is an odd integer, if we added one to this integer it would become even and then if we added one again it would become odd again. With this said
x --> first odd integer
x + 2 --> second odd integer
We want these integers to equal -28 so:
x + (x + 2) = -28
2x + 2 = -28
2x = -30
x = -15
Then we plug in x back into (x+2) to get the second integer
Car number 2 has a slope of exactly 2 while Car number one has a slope of 2.3 because it is not exactly on the 2 point line. Car 2 is steeper and Car two has better fuel efficiency
