Least to greatest - 1.8 , 1 , 1 2/5 , 1 9/10 , -1.25

-1.25, 1, 1 2/5, 1.8, 1 9/10

Step-by-step explanation:

-1.25, 1, 1 2/5, 1.8, 1 9/10

Step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
