A researcher is studying the relationship between the number of TVs owned by a family and the size of the family's electric bill

. After collecting data, he finds that the relationship is best modeled by the equation B = 2.43T + 95.66, where B is one month's electric bill in dollars and T is the number of TVs owned by the family. Which of these is a good interpretation of the y-intercept of this model?

Answer:

Step-by-step explanation:

No choice is given but here is the general interpretation.

Y-intercept is where the plot crosses the y-axia at x=0. In this case, x is T which represents number of TVs owned by the family. T=0 meaning there is no TV and B = 96.66 is the one month's electric bill in dollars for all other appliances in the home.

Given function

B=2.43T+95.66

Now

Compare to slope intercept form y=mx+b

Slope=m=2.43
Y intercept=b=95.66

Here y intercept may be the fixed charge .
