Question

Martin wants to plot a graph to show the price of different numbers of helmets. He has to plot the following points:

(1, 24.97), (2, 49.94), (3, 74.91), (4, 99.88)

Which of the following best describes how the y-axis should be labeled?

From 0 to 300 at intervals of 50

From 0 to 100 at intervals of 25

From 0 to 500 at intervals of 100

From 0 to 80 at intervals of 10

Answer 1

Which makes the most sense? Only one has a value that's close to the highest y value in the given points (1, 24.97), (2, 49.94), (3, 74.91), (4, 99.88)

Answer 2

Points are given as (x, y) btw. So find the highest y-value, and base your choice on that.

Answer 3

its either B or C

Answer 4

Tell me the maximum y-value in your points?

Answer 5

um, 99.88

Answer 6

So that's around what you want your maximum to be.

The interval has nothing to do with the maximum value, the interval tells where the tick marks will go on the axis.

Answer 7

ok so C or B

Answer 8

From 0 to 100 at intervals of 25

From 0 to 500 at intervals of 100

Which of these has a max at around 99.88? Read what I said about intervals.

Answer 9

intervals at 100

Answer 10

"The interval has nothing to do with the maximum value, the interval tells where the tick marks will go on the axis."

Answer 11

so intervals at 25

Answer 12

Ignore the intervals altogether.

Answer 13

From 0 to 100

or

From 0 to 500

Answer 14

to 100

Answer 15

right?

Answer 16

There's a reason I gave you a medal :)
