Answer:
y = 2x
Step-by-step explanation:
Formula is y = mx + b
m is slope
slope = (4 - -2) / (2 - -1) = 6 / 3 = 2
Now equation is y = 2x + b
To find b, substitute one of the coordinates in the equation. Let's use (2,4)
y = 2x + b
4 = 2(2) + b
b = 0
So equation is y = 2x
You have $15 and admission is $5, so you know have $10 before doing any games. If you wanted to play 12 games, you would need $10.20, which you do not have. But, if you wanted to play 11 games, then you would need $9.35, which is just under $10.
So the maximum amount of games that you could play would be 11 games.
Following with the extra hint that x = 82.03 m
There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:
Plug x = 82.03
=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m
Please take the time and understand the answer instead of just looking at the final result.
Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>
