48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220. So it would be about 48 points gained.
Answer: 
Step-by-step explanation:
The equation of the line in Slope-intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
Find the slope with this formula:

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

Substitute the slope and any point into
and solve for "b":

Then, substituting "m" and "b" into the equation
, you get that the equation of this line is:


Answer:
the answer to your question is c
M=Marissa's age
k=Kendra's age
k+2=m
m+2k=35
(k+2) + 2k=35
3k+2=35
3k=33
k=11
m=k+2
m=11+2
m=13
