Questions and Answers

2.

Find the distance between the points (3, -2) and (6, 4).
Correct Answer

A.

Explanation

The distance between two points in a coordinate plane can be found using the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) is equal to the square root of [(x2 - x1)^2 + (y2 - y1)^2]. Applying this formula to the given points (3, -2) and (6, 4), we have: distance = sqrt[(6 - 3)^2 + (4 - (-2))^2] = sqrt[3^2 + 6^2] = sqrt[9 + 36] = sqrt[45]. Therefore, the distance between the two points is sqrt[45].

If point S (4, 2) is the midpoint between points R and T, what is point R if the coordinates of T are (9, 17)?
- (-13, -1)
- (-1, -13)
- (4, 2)
- (8, 4)
Correct Answer

A. (-1, -13)

Explanation

The midpoint formula states that the coordinates of the midpoint between two points (x1, y1) and (x2, y2) is ((x1 + x2)/2, (y1 + y2)/2). In this case, we are given that point S (4, 2) is the midpoint between points R and T. We are also given that the coordinates of T are (9, 17). To find the coordinates of R, we can use the midpoint formula. Plugging in the values, we get ((x1 + 9)/2, (y1 + 17)/2) = (4, 2). Solving for x1 and y1, we get x1 = -1 and y1 = -13. Therefore, the coordinates of R are (-1, -13).

5.

If the distance between the points (2, 9) and (5, y) is , what are the possible values of y?
- 4 and 14
- -4 and -14
- -4 and 14
- 4 and -14
Correct Answer

A. 4 and 14

Explanation

The distance between two points 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. In this case, the x-coordinate of the first point is 2 and the x-coordinate of the second point is 5. Since the x-coordinate difference is 3, the y-coordinate difference must also be 3 in order for the distance to be a whole number. Therefore, the possible values of y are 9 + 3 = 12 and 9 - 3 = 6. So, the correct answer is 4 and 14.
