F(3) = 2(3)+6
f(3)= 6+6
f(3)=12
Hope this helps!
The slope is negative. the slope is calculated by using “rise over run”. in the problem, you go down 2 and over 1. so your answer is -2/1 or -2
Max's deck also has 40 blue cards, and for every 5 blue cards in his deck there are 9 red cards. His blue cards can be divided exactly into 8 groups (8 times 5 is 40), so he should also be able to divide his red cards into exactly 8 groups of 9 cards each. So there are 72 red cards in his deck (8 times 9 is 72).
This is in the form of a slope formula where y=mx+b. B pretty much gives you the vertical shift. Meaning that y=2/x-3 would be correct.
