To the nearest square foot is the same as to the nearest whole number. That would be 63.
Answer: 5/3
(1/3)(5/1)=5/3
Okay, here we have this:
Considering the provided information and that a positive correlation refers to the fact that as one increases the other also increases, we obtain that:
As more calories are eaten, it influences that the weight also increases, it means that there is a positive correlation.
Y as function of x
y=f(x)
that just means y=-2x+3
that is form y=mx+b
m=slope
b=y intercept
so then
y=-2x+3
the y intercept is 3 so go up 3 units on the y axis from the center (0,0) and put a point there
the slope is -2
so slope is rise/run
rise/run=-2=-2/1
so go down 1 units and go right 1 unit
put another point there
we get the opints (0,3) and (1,1)
connect them
see graph below
You can find the answer yourself. It is not that hard, just talk to your teacher.
