What is the function rule for the line?

f(x)=−3/2x+2

f(x)=−3/2x−2

f(x)=−2/3x−2

f(x)=3/2x−2

Step-by-step explanation:

To find the equation that represents the line, we just need to use two points on the line and find the slope first.

We are gonna use points (-3,0) and (0,-2). The slope formula is

Then, we use the point-slope formula

Therefore, the right answer is the third choice.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
