plot a scatter diagram and find the line of best fit.

OpenStudy (mathsucks321):

I hate these

OpenStudy (mathsucks321):

So we know it increases, I don't believe it is A or B. So that leaves us with C and D. The years go up by tens, so we just have to figure out how much the price is going up by each year right?

OpenStudy (welshfella):

the value of x will be the number of years after 1940

OpenStudy (mathsucks321):

So 100

OpenStudy (welshfella):

So for the year 2040 x will be 100

OpenStudy (mathsucks321):

So it is D

OpenStudy (welshfella):

D will give 1530*100 + 21,432

OpenStudy (3mar):

Yes, I agree with you @MathSucks321 It is not A nor B

OpenStudy (mathsucks321):

I know, I think I am right. Thank you @3mar

OpenStudy (welshfella):

D is correct the average increase in house prices is 1530 per year

OpenStudy (mathsucks321):
