Given:
The scatter plot and trend line.
To find:
Type of association, slope, equation of trend line and average cost of apple per pound.
Solution:
Form the given graph it is clear that the trend line passes through the two points (0,0) and (12,24).
Slope of trend line is
Slope of trend line is positive. It means, it represents positive correlation.
So, the type of association of the scatter plot is positive association.
Therefore, the slope of trend line is 2.
The trend line passes through (0,0) have slope 2, so the equation of the trend line is
Therefore, the equation of trend line is .
Slope of the line is 2.
Therefore, the average cost of apples per pound is $2.
add all the numbers until u left with no numbers left except the number left over and then add xs and then subtract the number from 23 to isolate x. then divide x by the number left over from the right side.
-6+9-19=-16
x+2x=3x
so -16+3x= 23
+16 +16
3x=39
(3/3)x=39/3
x=13
hope it helps!
