The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?

$2.19

Step-by-step explanation:

Given that :

Cost of 3 pounds of grape = $6.57

Cost in dollars = y ; number of pounds = x

Cost in dollars α number of pounds

Cost in dollars = k * number of pounds

k = constant of proportionality

$6.57 = k * 3

$6.57 = 3k

Divide both sides by 3

6.57 / 3 = 3k/ 3

2.19 = k

k = $2.19

step-by-step explanation:

stew:

we need to find the slope

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

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

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

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
