B y = 7  1/2

Step-by-step explanation:

If y varies directly with x

y = kx

If y = 3 and x = 8

3 = k*8

Divide by 8

3/8 = k

y = 3/8k

Now we want to know y if x=20

y = 3/8 * 20

y = 60/8

Divide top and bottom by 4

y =15/2

y = 7 1/2

7 1/2

Step-by-step explanation:

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
