M = y2-y1/x2-x1
m = 7- (-2)/ -6-(-7)
m = 9/1
slope = 9

Answer:
4/45
Step-by-step explanation:
First find all the pairs that make 9 that are two digit:
1+8
2+7
3+6
4+5
5+4
3+6
2+7
1+8
That's 8 pairs, and as there are 90 two digit numbers, 8/90 is the answer. but if you want to simplify, the answer is 4/45
X= 105
explanation:
45+30=75
180-75= 105
Multiply the investment fraction by the corresponding return, and add the products. The given fractions add to 59%, so the remainder is 41%. (The total of the fractions is 100%—all of the portfolio.)
... 0.43*9.1% + 0.16*16.7% + 0.41*11.4%
... = 3.913% + 2.672% + 4.674% = 11.259%
