Answer:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Step-by-step explanation:
The data given on this case is:
x: 14,12,20,16,46,23,48,50,55,50
y: 24,24,28,30,80,30,90,85,120,110
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
