The slope of the linear equation is 0.1998, and it means that the calories in a beef hot dog is increasing with the rate of 0.1998 calories per milligram of sodium.
Step-by-step explanation:
Using y = mx + b, we know that m represents the slope.
Looking at the equation of c = 0.1998s + 76.4520, our m is equal to 0.1998.
This slope means that the rate is increasing by 0.1998 calories for every milligram of sodium.
