Nancy wants to make a graph to show the relationship between the temperature of water, in degrees Celsius, and the time, in minutes, 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:
1.Label origin as (0, 0).
2.On x-axis, label Time in minutes.
3.On y-axis, label Temperature in degrees Celsius.
4.The scale on x-axis starts from 0 and goes up to 5 at intervals of 1.
5.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 x-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 x-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.
I think its b pls help me
wrong
Actually, the correct answer is option C: "It will not be spread out horizontally across the entire coordinate plane because in Step 2, Nancy plotted time instead of temperature on the x-axis."
In Step 2, Nancy should have labeled the x-axis as "Time in minutes" instead of "Temperature in degrees Celsius". The x-axis is meant to represent the independent variable in this case, which is time, while the y-axis represents the dependent variable, which is temperature.
You are correct. The answer is (b) "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."
By following the steps given, Nancy correctly labels the origin as (0,0) in step 1. In step 2, she labels the x-axis as "Time in minutes." In step 3, she correctly labels the y-axis as "Temperature in degrees Celsius."
However, in step 4, Nancy selects a scale on the x-axis that starts from 0 and goes up to 5 at intervals of 1. This means that the x-axis will only show values from 0 to 5, while the data points provided go up to 4. Therefore, the graph will not be spread out horizontally across the entire coordinate plane.
On the other hand, in step 5, Nancy selects a scale on the y-axis that starts from 0 and goes up to 200 at intervals of 50. This scale is suitable to accommodate the range of temperature values provided in the data points. Therefore, the graph will be spread out vertically across the entire coordinate plane.
Hence, the correct answer is (b).
