Answer:
16 people
Step-by-step explanation:
First subtract the cost of the rental from the amount of money:
$400-$150 = $250
Therefore Tia has $250 to spend for additional people. Then if each person is $15, divide the remaining amount of money by the amount of money per person:
$250/$15 = 16.67
Since you can't have 0.67 of a person she can have 16 people go with her.
This can also be modeled by this inequality:

Answer:
-1
Step-by-step explanation:
Let's use the formula!
6 - 3 = 3
-4 - (-1) = -3
The slope is -3/3 or -1
So, the equation is y=mx + b and you want to solve for b to find the y intercept.
-5=2(4) + b
-5=8+b
subtract the 8
-13=b
the equation is y = 2x - 13
