6th Grade Independent and Dependent Variables Quiz: 10 Questions with Explanations

A the poundsB the price per poundC the costD the store

The cost depends on the number of pounds, so the cost is dependent.

A \(y = x + 6\)B \(y = x + 5\)C \(y = 6x\)D \(y = \frac{x}{6}\)

y is 6 times x each time.

A 13B 36C 5D 9

\(4 + 9 = 13\).

A \((4, 7)\)B \((3, 6)\)C \((12, 4)\)D \((4, 12)\)

\(3 \times 4 = 12\), so (4, 12). (4, 7) is on y = x + 3.

A \((0, 0)\)B \((0, 2)\)C \((2, 2)\)D \((1, 1)\)

When x = 0, y = 0, so the line passes through the origin.

A \(c = d + 45\)B \(c = 45d\)C \(c = \frac{d}{45}\)D \(c = 45 – d\)

Cost = price per day times days.

A Ana earns $6 each hourB Ana has 6 times as many stickersC Ana runs 6 miles each dayD Ana is 6 years older than her brother

The other choices multiply by 6.

A 8B 35C 200D 45

\(40 \div 5 = 8\).

A x = 1, 2, 3 and y = 2, 4, 6B x = 1, 2, 3 and y = 3, 4, 5C x = 1, 2, 3 and y = 1, 2, 3D x = 1, 2, 3 and y = 3, 6, 9

Add 2 to each x: 3, 4, 5.

A \(y = 5x\)B \(y = x + 5\)C \(y = x – 5\)D \(y = \frac{x}{5}\)

Starting at 5 and adding 1 each step gives y = x + 5.
