Answer:

Step-by-step explanation:
We have to use the slope formula: m = slope
(x1, y1) = coordinates of the first point in the line
(x2, y2) = coordinates of the second point in the line
Here, we'll plug into our given points to give; 
Solving this, we get,
, but we're not done, as this fraction can be reduced.
Diving both sides of the fraction by 2, we get our final answer of
.
Convert pounds to kilograms.
1 pound = 0.4536 kg.
170 pounds x 0.4536 = 77.11 kg.
Multiply weight by grams of protein per kg.
77.11 kg x 1.4 =107.95 grams. Round answer as needed.
