HELP!!! I have no idea and its a long question.

1) The data in the table below represents the pressure of the gas as the temperature changes. Plot a graph of the data, using the space below. Draw a trend line and calculate its slope. How are the variables related? What will he pressure of the gas be at 0C?

the graph looks like this
Temperature Pressure
10 723
25 763
40 800
55 845
80 900

Do you have excel?

anonymous · Answer

no? what is that

anonymous · Answer

it's a computer program

anonymous · Answer

oh no

:(

anonymous · Answer

well that would be a great program to use to do this sort of work. however, I used it for you to plot the graph and add a trend line. the equation it came up with was 
y = 2.5522x + 699.01

anonymous · Answer

how would i graph that on the graph? 
i attached what the graph and everything looks like

anonymous · Answer

Ok just pick your first value and along the x axis go right to 10 and up to 723

anonymous · Answer

then repeat for all values of x and y

anonymous · Answer

you are probably going to have to determine slope from your graph and not use the equation I gave you. I would use the equation 

$$y-y_0 = m(x-x_0)$$

anonymous · Answer

thank you:)

anonymous · Answer

No problem and good luck! Chem can be tricky but if you keep up with it you can do it!
