Question 114088: Match the graph with one of the equations.
I can't get the graph in the question, but I do not understand how to determine which equation might match it anyway.
If it helps, the equations are:
y = -3x + 1
y = -1/3x + 1
y = 3x + 1
y = 1/3x + 1
Please help me understand how to determine which equation might match the graph picture in my problem.
Thanks!

Question 115342: Along the way to the new location- you find that all the temperatures provided are in °F. You will now continue your observations- that you had done previously. To do so, you will need to solve a linear equation. The linear equation that relates °C to °F is as follows:
°F = 1.8 °C + 32.0
The following data was calculated in this way:
Temperature °F Miles east from starting point
85.2 0
84.5 15
83.6 25

Provide a plot of temperature versus distance east
Use the graph to determine the expected temperature at 75 miles east
I am completely lost on this problem, I know how to make a graph but I don't understand what they are asking for... could someone give me a little insight in solving this problem.
