Answer:
(y1-y2)/(x1-x2)
Step-by-step explanation:
if you have two points from the graph then you can use them to find the slope, for example:
(2,3) and (0,5)
you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:
3/2 and 5/0
Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):
3-5/2-0
Then you solve:
-2/2
-1
which means that -1 is the slope for this
(the "/" is a fraction bar, in case you didn't already know that)
<span>The following choices may have a negative correlation: - speed of a car and minimum stopping distance - average running speed and total race time - outside temperature and amount of a heating bill
<span>Theses factors may yield negative results depending on the variables that will be present in a controlled experiment.</span></span>
If the signs are alike, and ur adding/subtracting......u add them and keep the same sign
The answer is 54.
The area of one square side is: 3 x 3 = 9
There are 6 sides on a cube so: 9 x 6 = 54
