Which set is a function? 1) (3,4),(3,5),(3,7),(3,9)
2) (5,4),(1,3),(3,9),(5,6)
3) (0,2),(4,5),(0,10),(6,7)
4)(1,4),(2,5),(5,2),(4,1)

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

the answer is 13 cm

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
