Suppose the value of some quuantity Y, in year 0 was Y0. Suppose the following year, it was Y1. Then year over year percantage change is = 100*(Y1/Y0 -1).

x1 + x2 / y1 +y2
The distance between (x, y1) and (x, y2) is abs(y1 - y2) or |y1 - y2|.
The slope of a line between Points 1 and 2 is defined as m = (Y2 - Y1) / (X2 - X1) where coordinates for Point 1 is (X1,Y1) and Point 2 is (X2,Y2). So if the value of Y2-Y1 = 0 then the Slope is zero. If the value of X2 - X1 = zero then the equation is undetermined because you can't solve an equation with a 0 value in the denominator. or m = (Y2 - Y1) / 0
No because the slope is: (y1-y2)/(x1-x2)
You can use Pythagoras to solve this to get the co-ordinates. from Pythagoras we have a^2 + b^2 = c^2 For this a and b will be the x and y distance and c the distance between the 2 points so we get (7-2) ^2 + (8-y1)^2 = 13^2 So we need so solve this to get a correct solution which is (8-y1)^2 = 144 so 8 - y1 = + or - 12 so y1 = -4 or y1 = 20
The change in the y-value over the x-value, the slope, m, (y1-y2)/(x1-x2).
There are many calculations that could be done: =SUM(Y1:Y10) =AVERAGE(Y1:Y10) =MAX(Y1:Y10) =MIN(Y1:Y10) =COUNT(Y1:Y10)
5x-y1 = 4
(Y2-Y1)/(X2-X1) Where Y2= second Y value (6) Y1= first Y value (5) same for X values (6-5)/(8-2)=1/6
