I am working on setting a formula equal to another-the first formula is A=1.2P and the 2nd the least squares regression line y=-2.433x +950.5. How can I set this equal to obtain a graph of the information
What do the variables in the formula A = 1.2P represent? Once you know what the variables represent, it may help with your next step.
A=acres of land and P=population
Do you know what the variable x represents in the least squares regression formula? If x represents the same variable as one of the variables in the formula A = 1.2P, then you might be able to set the formulas equal to each other by solving for the same variable in each case.
It has to be the acres of land as this is what information that I used for the reponse variable for the scatter graph. The explanatory value was t (time in years)
OK, since x = acres of land and A = acres of land, solve the least squares regression formula for x. Your formula will then be x =... instead of y = ...
Once you have solved the regression formula for x, you will then be able to substitute 1.2P for x because A = x. That should be it!
Thank you so much for your help-with your input I created a table with the variables and was able to "eyeball" the answer-thanks again!!!
