1. In a class, there are 12 students with blue eyes, 6 with green eyes, and 18 students with brown eyes. What is the ratio of green eyes to blue? What is the ratio of brown eyes to class?

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

20%

step-by-step explanation:

i think the answer is b. i hope i !
