Answer:
y = 25x, proportional relationship
Step-by-step explanation:
Let "x" = number of hours read (replace with "h" if that's the variable your teacher wants)
Let "y" = number of pages read (you can use any other variables if you want)
Let's first calculate the slope using 
with any two points, I'm going to use (2, 50) and (3, 75):
Our slope is m = 25.
Now we can use the point-slope form 
with our slope and any point (I'll use (2, 50)) to figure out the equation:
Simplify:
Since the slope is positive, the relationship is proportional.
Answer:
0-4
derivate first
function is missing
substitute the value of X
The correct answer is 21 simply because 21 is a multiple of 3 and a multiple of 7, other answer does not hold this conclusion.
A plane that has more than one agent
Graph A shows a positive linear association between x and y.
