1. which answer is the equation of the line represented in function notation?

2.given graph for function f (x) given above, find the f (-2). f (-2) =

Part 1)

Part 2)

Step-by-step explanation:

step 1

Find the equation of the line

Let

The equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem

The point B is the y-intercept

so

b=-2

Find the slope m

substitute

In function notation

step 2

Find f(-2)

substitute the value of x=-2 in the function

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

you first to choose the points and then move from then as the slope you have
