Ok so grapes,
We have 4 servings and 9.88 grams total, so to find one serving we just need to divide by 4.
9.88/4 = 2.47 per serving
This is a linear function, of the kind y = mx + b
where x is the number of visit, b is the weight when x = 0, and m is the predicted change of weight for every visit.
m = - 4 ounces / visit, which must be converted to pounds (the negative sign indicates that the change is a decrease)
1 lb = 16 ounces = 4 ounces = 0.25 lb
Then m = - 0.25 lb / visit.
Now, for x = 1, y = 126 => 126 = - 0.25(1) + b => b = 126 + 0.25 = 126.25
Then the function is y = 126.25 - 0.25x
Now round to the nearest tenth:
y = 126.3 - 0.3x
Answer: y = 126.3 - 0.3x
That menas that it we be negative because any thing that is negative is going bigger
Answer
x=3 or (3,0) and if you need it y=-2x+3
