Andrew= 4 yr.old
Sara=12 yr. old
Tom= 12 yr. old
Basically, what I did was guess and check, but there are other ways also. When I came with Andrew's age of 5 and it was pretty close, I went down to 4 years old and that worked perfect because that way both Tom and Sara are 12 years old.

Answer:
Plot these points
(1,935)
(2,870)
(3,805)
(4,740)
(5,675)
Slope= -65
y intercept = 1000
and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away
Step-by-step explanation:
Just graph these points which you can get by plugging in the numbers
1000-65= 935
(1,935)
1000-65*2=870
(2,870)
1000-65*3= 805
(3,805)
1000-65*4=740
(4,740)
1000-65*5= 675
(5,675)
B:
y= mx+b where m is the slope and B is the y intercept
we can re write the equation as follows
-65x+1000
It's pretty clear that -65 is the slope and 1000 is the y intercept
B, y=3x-2. It’s a positive line, so it can’t be C. The line intersects the y axis at -2 so we know it’s either B or D. If you count the points the line runs through, you can see it rises 3 points and only runs 1. That means the slope is 3/1 which equals 3. B’s slope is 3, so you have your answer!
