Question

Bryan's puppy has been gaining weight for the last year. The graph shows data about the puppy's weight over time.

Answer 1

Answer:

Option 2. 25 pounds

Step-by-step explanation:

As per graph weight gain of Bryan's puppy is represented by a linear function which is a straight line.

Therefore equation of the line will be y = mx + c

to calculate the value of m we will take two points (endpoints) on the line (0, 0) and (50, 6)

So m = (50-0)/(6-0) = 50/6 = 8.33

since this passes through (0, 0) so c = 0

Equation will be y = 8.33x

Now we have to get the value of y (weigh of puppy) at x = 3.

y = 8.33×3 = 24.99 ≈ 25 lb.

Option 2 is the answer.

Answer 2

I would say 25 pounds because the graph displays a proportional relationship( a straight line) so the next point in the line would be 25 pounds.
I hope this helped! :-)
