Direct relationships are used to represent linear functions that pass through the origin.

The direct proportional relationship of the tables are: y = 15x

and

.The unit rates are 15 pieces in 1 candy box, 4 lemons in 1 glass and 23 gallons in 1 minute

Part (a) The equation that represents the direct proportional relationship

A proportional relationship is represented as:

y = kx

Where the proportionality constant (k) is calculated using:

$k = \frac yx$

From the tables, we have the following points:

Table 1:

.Table 2:

.Table 3:

So, the proportionality constants for the tables are:

Table 1: $k =\frac{150}{10}=15$ Table 2: $k =\frac{24}{6}=4$ .Table 3: $k =\frac{138}{6}=23$ .

Substitute values for k in y = kx .

So, the direct proportional relationship of the tables are:

Table 1:

Table 2:

Table 3:

Part (b) Describe the unit rates

Table (1) represents the pieces of candy in the box of candies.

So, the unit rate is 15 pieces in 1 candy box

Table (2) represents the lemons used for glasses of lemonade

So, the unit rate is 4 lemons in 1 glass

Table (3) represents the gallons of water used in minutes

So, the unit rate is 23 gallons in 1 minute

Answer/Step-by-step explanation:

Equation representing a direct proportional relationship is given as y = mx

Where, unit rate (m) = y/x

Use the above to solve the problems given

PART A:

1. First, find m using a pair fo values from the table, say (2, 30)

m = 30/2 = 15

Substitute m = 15 into y = mx

Equation would be:

y = 15x

2. Find m using (2, 8)

m = 8/2 = 4

Substitute m = 4 into y = mx

Equation would be:

y = 4x

3. Find m using (3, 69)

m = 69/3 = 23

Substitute m = 23 into y = mx

Equation would be:

y = 23x

PART B:

1. Unit rate is 15 pieces of Candy per box of Candy

2. Unit rate is 4 Lemons used per glass of Lemonade

3. Unit rate is 23 gallons of water used per minute
