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 point: (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.
