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: 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

Respuesta :

The correct option is this: IT WILL NOT SPREAD OUT VERTICALLY ACROSS THE ENTIRE COORDINATES PLANE BECAUSE IN STEP 5 NANCY SELECTED AN INCORRECT SCALE ON THE Y AXIS.
Firstly, the boiling point of water is 100 degree Celsius and the highest point on the Y axis is 90 yet Nancy went ahead and chose up to 200 on her Y axis; that is wrong.
Secondly, the interval of 50 between each point is too much especially compared to the scale she chooses for the X axis.
The best thing she ought to do is to make 100 her highest point on the Y axis and make 10 to be the interval between the points.
