Answer: (a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5
(b) The unit rate is 3.5 cm/s since the rate is constant.
(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.
Step-by-step explanation:

Part B:
Number of tents|||Number of people
1 |||7
6 |||42
9 |||63

Part C:
Tents=x
1x=7 people
Step-by-step explanation:
Hi there,
The sum of two numbers is 8.
x + y = 8
If three times the first number
is equal to the second number.
3x = y
Replace the y in top equation with 3x
x + 3x = 8
4x = 8
x = 2
Substitute x = 2 in first equation
x + y = 8
2 + y = 8
y = 8 - 2
y = 6
{2,6}
Hope this helps :-)
The answer is 1.
If you put -1 instead of x, then you can get 1.
2(-1)+3=y
-2+3=y
1=y
