Question 1164104: he following line graphs estimate the global temperature rise between the years of 2010 and 2040. Find the average rate of temperature change (the slope) of Model A: Status quo (in °C per year).
A line graph has "Year" on the horizontal axis and "Temperature rise (°C)" on the vertical axis. There are four models given and four lines.
The models are as follows.
Model A: Status quo
Model B: Shift to lower carbon fuels (natural gas)
Model C: Shift to renewable sources (solar, hydro, and wind power)
Model D: Shift to nuclear energy
The lines are as follows.
The line labeled A starts at 2010 on the horizontal axis and 0 on the vertical axis. It goes up and right to 2040 on the horizontal axis and 1.4 on the vertical axis.
The line labeled B starts at 2010 on the horizontal axis and 0 on the vertical axis. It goes up and right to 2040 on the horizontal axis and 1.0 on the vertical axis.
The line labeled C starts at 2010 on the horizontal axis and 0 on the vertical axis. It goes up and right to 2040 on the horizontal axis and 0.9 on the vertical axis.
The line labeled D starts at 2010 on the horizontal axis and 0 on the vertical axis. It goes up and right to 2040 on the horizontal axis and 0.7 on the vertical axis.

A is (2010, 0) and (2040, 1.4). That slope is 1.4/30 or 0.0467 C. per year.
