Answer:
You will likely need to actually measure a few people for parts 1 and 2, but the statement in part 2 should be something like "The length of the forearm of one person will be very similar to the length of their foot" or "As the length of the forearm increases, the length of the foot will increase in similar amounts".
Since the equation in pt.3 is y = 0.860x + 3.302, if x=17, then 0.860(17) + 3.302=17.922
The next question is dependant on pt.1
The data from pt.1 should be somewhat similar to the data you collected, the values between them are different because of the allowed error margin between the two.
The data can be made into a function using the "line of best fit". The equation in part A represents a function because there are no two points where two y coordinates are on the exact same x coordinate.

h(x)=5-7x²
h(-1)=5-7×(-1)²

That's going to depend completely on the unit of
the 4.5 which, sadly, you have not mentioned.
Answer is b
there are 2 cases
1: if x is less than -5/3
then you have -3x-5=5x+2
solve and get x=-7/8 which is invalid
2: if x is more than -5/3
then you have 3x+5=5x+2
solve and get x=3/2 which is valid
so b is the answee
Yessssssssssssssssjsahahhaahahha
