The scatter plot shows the relationship betweeen the number of hours students spend watching television and the numer of hours they spend with family each week.

what is the y-intercept of the line of best fit and what does it represent?

11.5 hours; the number of hours students spend with family in a week when they do not watch television
9.2 hours; the number of hours students watch television in a week when they do not spend time with family
9.2 hours; the number of hours students spend with family in a week when they do not watch television
11.5 hours; the number of hours students watch television in a week when they do not spend time with family

B. 9.2 hours; the number of hours students watch television in a week when they do not spend time with family

Step-by-step explanation:

We are given,

The x-axis represents the time spent with family and the y-axis represents the time spent on watching television.

Now, y-intercept is the point where the scatter plot crosses y-axis.

From the scatter plot and and according to the options, the data point is located at x= 0 and y= 9.2.

So, option B is correct.

x=30

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
