Negative linear association is like inverse variation or a negative slope
we got
s=-0.5t+3.6
3.6 is the value of s when t=0
that means when they spent 0 hours watching tv, they spend 3.6 hours doing homework
that could mean that they have 3.6 free hours to do homework or watch tv
<span>y = 2x + 20. The answer is A. Explanation: Vlad spends a known amount of time on his history homework (20). On top of it, he also spends an unknown amount of time on solving a number of math problems (x). Each problem takes two minutes to solve, so the amount of time that he spends solving math problems is 2*x or 2x. In total (y), Vlad spends 20 + 2x amount of time on his homework. So y = 2x + 20, where y is clearly greater or equal to 20 and x is greater or equal to 0.</span>

We need to check the ordered pairs for x = -2, x=5, x= 2/3 and x = 0.75.
1. For the first function: y = 9-4x
x=-2

The ordered pair is (-2,17).
x = 5

The ordered pair is (5,-11).
x = 2/3

The ordered pair is (2/3, 19/3)
x = 0.75
