Interpreting Points on Graphs of Proportional Relationships

There are the following conclusions:

Not true

  1. The pumpkin grew to a weight of 3 ounces in 18 weeks.
  2. The quotient 3 / 18 equals the growth rate of the pumpkin in ounces per week.

Cannot be determined

  1. Each crate can hold 18 pumpkins.

True

  1. In 3 weeks, the pumpkin grew to a weight of 18 ounces.
  2. The pumpkin grew at a rate of 6 ounces per one week.

<h3>How to interpret graphs of proportional relationships</h3>

The graph shows the graph of proportional relationship, in which the weight of a pumpkin, in ounces, is directly proportional to time, in weeks. Then:

y ∝ x

y = k · x

Where k is the constant of proportionality, in ounces per week.

The point (x, y) = (3, 18) indicates that a pumpkin reaches a weight of 18 ounces after 3 weeks and the constant of proportionality is equal 6 ounces per week.

Then, we have the following conclusions:

Not true

  1. The pumpkin grew to a weight of 3 ounces in 18 weeks.
  2. The quotient 3 / 18 equals the growth rate of the pumpkin in ounces per week.

Cannot be determined

  1. Each crate can hold 18 pumpkins.

True

  1. In 3 weeks, the pumpkin grew to a weight of 18 ounces.
  2. The pumpkin grew at a rate of 6 ounces per one week.

Alona [7]

Based on the information provided and the requirements to organize the students, Jon most likely has 23 students.

<h3>How many students are needed to organize them in a rectangular grid?</h3>

In general, Jon will need a number that is not prime as this type of number will not allow him to complete all the grid.

<h3>Which are possible numbers?</h3>

20 = A rectangular grid of 5 x 4 seats can be arranged

21= A rectangular grid of 7 x 3 can be arranged

22 = A rectangular grid of 2 x 11 can be arranged

23 = It is impossible to organize 23 seats in a rectangular grid without gaps

Find the slope line (- 6, 1), (4, 8)
AVprozaik [17]

Answer:

The slope is \frac{7}{10}

Step-by-step explanation:

☆Remember:

m =  \frac{y_2 - y_1}{x_2 - x_1}

☆We just plug in now!

m =  \frac{8 - 1}{4 - ( - 6)}  =  \frac{7}{10}
