In the Census, each household can identify itself as either a "family" household or a "non-family" household. Examples of a non-family household are single person households and groups of students who share a house. Alameda County has hundreds of thousands of households, of which 65% are family households. The rest are non-family households. San Francisco County also has hundreds of thousands of households of which 44% are family households. A simple random sample of 400 households is taken in Alameda County. Independently, a simple random sample of 400 households is taken in San Francisco County.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

what shape is
