Answer:
72/107
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (-1 -71)/(-100-7)
= -72/-107
= 72/107
The answer is 176 because 86+86=176

The midpoint for this question is (2,1)
Answer:
The answer is below
Step-by-step explanation:
Let us assume that the age of Greg's brother (Gabe) is x years, and let Greg's age by y years. Since Greg is 10 years older than his brother gabe, then:
y = x + 10 (1)
Also. Greg is 3 times as old as Gabe, hence:
y = 3x (2)
From equation 1 and equation 2:
y = x + 10 = 3x
Hence:
3x = x + 10
Subtracting x from both sides gives:
3x - x = x + 10 - x
2x = 10
Dividing by 2:
2x/2 = 10/2
x = 5 years
y = x + 10 = 5 + 10 = 15 years
Therefore Gabe is 5 years old and Greg is 15 years old
