2. Seven students are planning to take an exercise class. If the cost is $12 for each student, how much will it cost for all 7 students to take one class? A) $80 B $82 $84 O $86

$84

Step-by-step explanation:

Their 7 students

$12 for each students per class

12 × 7= 84

it would be 84

Step-by-step explanation:

easy explanation just multiple.

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
