To graph a line with a slope of 1/5 and passes through the point (-2,2), you would first need to graph the point (-2,2).
Once you have done that, all you need to do is apply the slope. With a slope of 1/5, what you would do is go up 1, and over 5.
Then mark the point that you land on, which would be (3, 4).
Keep using the slope to find points, then draw your line.
Hope this helps!
The greenhouse effect is related to the increase in the average surface temperature which is considered "global warming". Global warming is the result of an increase in gases like methane, carbon dioxide, and other factors that lead to a rise in the planet's temperature.
