Answer:
((-9 - 1)/2, (-4 + 6)/2) = (-5,1)
((-5 + x)/2, (1 + y)/2) = (-4,-3)
(-5 + x)/2 = -4
-5 + x = -8
x = -3
(1 + y)/2 = -3
1 + y = -6
y = -7
(-3,-7)
The slope of a line in standard form is given by -A/B do for this line we get -8/9. since parallel line have the same slope the answer to the question is -8/9 also
Answer:
it may be A log x ........
Based on the data, the most likely correlation coefficient would be -1.
The slope between 20 and 30 days is -1, and it represents the change in the surface area of the lake per day.
The data represents correlation, not causation.
Since the data would form a perfectly straight line through the points, the correlation coefficient would be -1 for a perfect decreasing fit.
To find the slope, find the change in the surface area between those days, the change in the days, and write it as surface area/days: 80-90=-10; 30-20=10; -10/10=-1
This is not causation because there could be lurking variables we cannot see.
The quotient is 2x^2-5x+2
