Answer:
Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
120° is the correct answer<span />
Cant really see it like that
Answer:

Step-by-step explanation:
The gradient = change in y / change in x
When the x value increases by 1, the y value decreases by 2 so -2 / 1 = -2
The y intercept is 4, so it is +4
To help solve this problem, create a simple equation.
Let x = weekly allowance.
(x/2) + $4 = $11. Subtract 4 from each side
(x/2) = 7. Multiply each side by 2
x = $14.
Joe's weekly allowance is $14
