First we calculate the slope (which is called "m".
Slope = m = (Y2 -Y1) ÷ (X2 -X1)
m = (-8 -1) / (5 -2) = -9 / 3 = -3
We next fill in this equation: b = y -mx
We know m = -3 and we can choose a point (2, 1) to calculate "b"
b = 1 --3 * 2 b = 7
Putting this into y = mx +b
y = -3x +7
Answer:
increase
Step-by-step explanation:
increase because it's going up
Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
Answer:
Step-by-step explanation:
You cannot solve the problem because it doesn't have an equal sign, but I suppose you can simplify it. Look at this screenshot, it may help:
