Question

Help please!

Answer 1

Nancy wants to make a graph to show the relationship between the temperature of water, in degrees Celsius, and the time, in seconds, for which water is heated. She plots the following points:

(0, 50), (1, 60), (2, 70), (3, 80), (4, 90)

She uses the following steps to plot the graph:

Label origin as (0, 0).
On x-axis, label Time in minutes.
On y-axis, label Temperature in degrees Celsius.
The scale on x-axis starts from 0 and goes up to 5 at intervals of 1.
The scale on the y-axis starts from 0 and goes up to 200 at intervals of 50.



Which of the following best describes the graph?

It will not be spread out horizontally across the entire coordinate plane because in Step 4, Nancy selected an incorrect scale on the axis.

It will not be spread out vertically across the entire coordinate plane because in Step 5, Nancy selected an incorrect scale on the y-axis.

It will not be spread out horizontally across the entire coordinate plane because in Step 2, Nancy plotted time instead of temperature on the axis.

It will not be spread out vertically across the entire coordinate plane because in Step 3, Nancy plotted temperature instead of time on the y-axis.

Answer 4

I did but I posted it again. @Librarian

Answer 5

Ok I will see if I can help you out im not the best at math but hay theirs a first for everything right?

Answer 6

Of course!

Answer 7

I believe it would be C I could be wrong though I will ping some "mathletes" and see what they think.

Answer 10

Answers.com says


The closest thing I can think of is that perhaps the water will not got any hotter after some time period, so that there is only a limited range of temperature values on the y axis, but this is not because the y scale is incorrect.

Answer 11

your question is long repost what you need to have answered

Answer 12

i think it's b. i don't see why the values need to go up to 200. it only needs to go up to 100

Answer 13

(0, 50), (1, 60), (2, 70), (3, 80), (4, 90)

On y-axis, label Temperature in degrees Celsius.
The scale on x-axis starts from 0 and goes up to 5 at intervals of 1.
