The curriculum committee at Larchmont High School wants to offer a new elective course next year. They decide to survey Larchmont's 1500 students to determine which course students would prefer. The choices are History of Art, Robotics, and Money and You. Which of the following survey methods will allow the committee to make a valid conclusion about which course the students at Larchmont prefer?

B

Assign a number to each student, and use a computer program to generate 150 random numbers between 1 and 1500. Ask those students whose numbers are selected.

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
