Answer:
x =8
Step-by-step explanation:
For two lines to be parallel, their slope must be the same.
To find the slope, we can use the form:
For the top line, the change in height (y value) can be seen as a - 0 or simply a, and the change in base is just -b (because our
is just 0, from the origin.
Hence, line 1's gradient is:
Now, we can repeat this process for line 2:
Change in height is -d, change in base is c
Hence, line 2's gradient is:
For the two lines to be parallel, both gradients must be the same:
As, given correlation coefficient for your data set is= -0.015
It means there is weak relation between two variables.If value of correlation coefficient is near to 1 or -1, it shows there is strong correlation.
Negative correlation means, if one quantity is increasing other is decreasing.So, the value of -0.015 shows that there is very less correlation between x and y values or two values in data set.
So, the chances are very less that predicted value will be reasonably close to the actual value as the points will be far from line of best fit.
