Step-by-step explanation:
what is the problem ? find the slope of the line ?
the slope is the ratio y/x of the y difference and the x difference between 2 points.
I see 2 points with seemingly integer coordinates.
one point is at (2, 6) as you marked it also on the sheet.
the other point is (6, 12).
so, when you go from point 1 to point 2, x changes by 4 units (from 2 to 6) and y changes by 6 units (from 6 to 12).
therefore, the slope is 6/4 = 3/2
Use the formula (zy)i<span> = (y</span>i<span> – ȳ) / s </span>y<span> and calculate a standardized value for each y</span>i<span>. Add the products from the last step together. Divide the sum from the previous step by n – 1, where n is the total number of points in our set of paired data. The result of all of this is the correlation coefficient </span>r<span>.</span>

Step-by-step explanation:
-4+5 equals 1 because on a number line -4 is left of 0, and positive 5 is right of 0. So therefore moving from -4 5 spaces right would put you at (pos) 1.
Answer:
It isn't?
Step-by-step explanation:
Step 1:
x + 8y = 21
x + 8y - 8y = 21 - 8y
x = -8y + 21
Step 2:
(-8y + 21) + 8y = 21
-8y + 21 + 8y = 21
21 = 21
