Answer:
y - 5 = 5(x - 1)
Step-by-step explanation:
Two points on the graph are (1, 5) and (7, 35). Going from the first to the second, we see x (the 'run') increasing by 6 and y (the 'rise') increasing by 30. Hence the slope of this line is m = rise / run = 30/6, or 5.
Using the point-slope equation, we get
y - 5 = 5(x - 1)
A large MAD (mean absolute deviation) tells us that there is a lot of variation in the ages of the swimmers. It tells us specifically that there are a lot of swimmers that are not close the to the age of 10 (which is the mean).
Answer:
X = 0, Y = -2
Step-by-step explanation:
5(2x + 6y = -12)
2(5x - 5y = 10)
10x + 30y = -60
10x - 10y = 20
40y = -80
y = -2
x = (10 + (-2)5) / 5
x = 0
