## Distance Formula Questions and Answers

• 1.

### The distance from (1, 0) to (x, 0) is equal to 1. While there is more than one possible x-coordinate for the second point, which of the following options satisfies the distance formula with the given coordinates?

• A.

-1

• B.

2

• C.

4

• D.

0

D. 0
Explanation
The distance between two points in a coordinate plane is given by the distance formula, which is the square root of the difference in x-coordinates squared plus the difference in y-coordinates squared. In this case, the y-coordinates are both 0, so the formula simplifies to the absolute value of the difference in x-coordinates. The distance from (1, 0) to (x, 0) is equal to 1, so the absolute value of the difference in x-coordinates must also be 1. The only option that satisfies this is 0, as the absolute value of the difference between 1 and 0 is 1.

### Distance can be negative.

• A.

True

• B.

False

B. False
Explanation
Distance cannot be negative because it is a scalar quantity that represents the length between two points. It is always a positive value or zero, as it measures the magnitude of displacement. Negative values are not applicable in the context of distance.

### The distance from (6,7) to (8,9) is equal to (leave your answer in a simplified radical form - i.e., no decimals)

• A.

2√2 units

• B.

3√2 units

• C.

8 units

• D.

√17 units

A. 2√2 units
Explanation
The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula:
d = √((x2 - x1)² + (y2 - y1)²)
In this case, the points are (6, 7) and (8, 9). Applying the distance formula:
d = √((8 - 6)² + (9 - 7)²)
d = √(2² + 2²)
d = √(4 + 4)
d = √8
So, the distance between (6, 7) and (8, 9) is 2√2 units.

### The distance from (-1,-2) to (3,4) is equal to (leave your answer in a simplified radical form - i.e., no decimals)

• A.

2√7 units

• B.

10√5 units

• C.

√2 units

• D.

2√13 units

D. 2√13 units
Explanation
The distance between two points in a coordinate plane can be found using the distance formula, which is the square root of the sum of the squares of the differences in the x-coordinates and the y-coordinates of the two points. In this case, the x-coordinates are -1 and 3, and the y-coordinates are -2 and 4. Using the distance formula, we get the square root of ((3-(-1))^2 + (4-(-2))^2), which simplifies to the square root of (16 + 36), which is the square root of 52. Therefore, the distance is 2√13 units.

### Which of the following is an appropriate label for distance?

• A.

Milliliters

• B.

Kilometers

• C.

Square inches

• D.

Pounds

B. Kilometers
Explanation
Kilometers is an appropriate label for distance because it is a unit of measurement specifically used to quantify length or distance. It is commonly used in many countries around the world and is a standard unit in the International System of Units (SI). Kilometers are used to measure long distances, such as the distance between cities or the length of a road. It is a suitable label for distance as it accurately represents the concept of measuring how far apart two points are from each other.

### Which of the following is NOT an appropriate label for distance?

• A.

Joules

• B.

Meters

• C.

Feet

• D.

Yards

A. Joules
Explanation
The label "Joules" is not an appropriate label for distance. Joules is a unit of energy in the International System of Units (SI), not a measure of distance. Meters, feet, and yards, on the other hand, are all units used to measure distance.

### Which of the following equations represents the distance formula? (Hint: there is more than one correct answer)

A.
B.
D.
Explanation
The distance formula represents the distance between two points in a coordinate plane. It is calculated using the Pythagorean theorem, where the square of the difference in the x-coordinates is added to the square of the difference in the y-coordinates, and then taking the square root of the sum. The equation that represents the distance formula is d = √((x2 - x1)^2 + (y2 - y1)^2).

### Find the distance between the two points (4, 1) and (10, 9) (leave your answer in a simplified radical form - i.e., no decimals)

• A.

√14 units

• B.

10 units

• C.

64 units

• D.

√28 units

B. 10 units
Explanation
The distance between two points can be found using the distance formula: √((x2 - x1)^2 + (y2 - y1)^2). In this case, the coordinates of the two points are (4, 1) and (10, 9). Plugging these values into the formula, we get √((10 - 4)^2 + (9 - 1)^2) = √(6^2 + 8^2) = √(36 + 64) = √100 = 10 units.
