Question 420665: Make a graph that shows when fahrenheit and celsius meet. I don't know what the x-axis or the y-axis should be. From the functions...
*C=(F-32)* 5/9
*F= C* 9/5 + 32 ,
I solved them and found out that on a graph, -40 is when the celsius and fahrenheit will meet. So, can you help me figure out what the graph would look like. What are the y-axis and x-axis? Thanks!
