Answer:
2500 meals in 20 hours.
Step-by-step explanation:
The easiest point to see is (2,250). The other point (since you need 2) is the origin. This is a graph. It does not require any greater accuracy than looking at the point that is chosen.
x = 2
y = 250
k = ?
y = k*x equation
250 total meals packed = k * 2 hours Substitute values
k = 250 /2
k = 125 meals / hour
Let x = 20 hours
k = 125 meals / hour
y = ?
y = 125 * 20
y = 2500 meals
X = 5 and y = -12 is in the fourth quadrant. Hypotenuse = 13
sin theta = opposite / hypotenuse = -12 /13
