Question

Segment AB the diameter of circle M. The coordinates of A are (-4,3). The coordinates of M (1,5) what are the coordinates of B

It’s number 4 but if you can answer all that would be even better

Answer 1

The correct answer is option 1) (6,7)

Explanation:

Points to remember

Mid point formula

Let (x₁, y₁) and (x₂, y₂) be the end points of a line segment, then the coordinates of the midpoint of the line segment is given by

[(x₁ + x₂)/2, (y₁ + y₂)/2]

To find the coordinates of B

Let A(x₁, y₁) = (-4, 3), and M(1, 5)

Coordinates of B be (x₂, y₂)

We have,

[(x₁ + x₂)/2, (y₁ + y₂)/2] = (1, 5)

(x₁ + x₂)/2 = 1

(-4 + x₂)/2 = 1

-4 + x₂ = 2

x₂ = 2 + 4 = 6

(y₁ + y₂)/2 = 5

(3 + y₂)/2 = 5

3+ y₂ = 10

y₂ = 10 - 3 = 7

Therefore coordinates of B(6,7)

The correct answer is option 1) (6,7)
