Let the two numbers be x and y.
We know that:
x+y=72
x-y=12
Sum the two equations:
2x=84
Divide both sides by 2:
x=42
Plug this value for x in one of the two equations:
42-y=12 ---> y=42-12=30
Look at points (0, -1) and (1, 5).
m = (y2 - y1)/(x2 - x1) = (5 - (-1))/(1 - 0) = 6/1 = 6
Slope = 6
Answer: 6
1/6, 1/3, 1/2, 2/4, 2/3, 3/4
Answer:
