A study was done to investigate the relationship between a new anti-inflammatory medicine and weight gain. The correlating linear model is shown below, where x represents the number of days on the medicine, and y represents the weight gain, in pounds. Interpret the slope.

A.
Not enough information is provided to interpret the slope.
B.
An additional 0.7 days on the medicine is associated with a pound of weight gain.
C.
An additional day on the medicine is associated with 0.7 pounds of weight gain.
D.
Zero days on the medicine is associated with 0.7 pounds of weight gain.

I couldn't find the graph anywhere, but I did find the equation

y = 0.7x

comparing this to y = mx + b, the slope is 0.7

since the slope is 0.7, for every 1 unit of the independent variable, the dependent variable increases by 0.7

apply this logic to the problem to determine the real-life meaning of this slope
