To find the midpoint between two points, we use the midpoint formula:
Midpoint = ((x₁ + x₂)/2, (y₁ + y₂)/2)
In this case, point A has coordinates (7, -4) and point B has coordinates (-9, 5).
Applying the formula:
Midpoint = ((7 - 9)/2, (-4 + 5)/2)
Midpoint = ((-2)/2, 1/2)
Midpoint = (-1, 1/2)
Therefore, the midpoint between point A and point B is (-1, 1/2).

To find the distance between two points, we use the distance formula:
Distance = √((x₂ - x₁)² + (y₂ - y₁)²)
In this case, point J has coordinates (-3, 2) and point K has coordinates (1, -6).
Applying the formula:
Distance = √((1 - (-3))² + (-6 - 2)²)
Distance = √((1 + 3)² + (-6 - 2)²)
Distance = √(4² + (-8)²)
Distance = √(16 + 64)
Distance = √80
Simplifying further:
Distance = √(16 * 5)
Distance = √16 * √5
Distance = 4√5
Therefore, the distance between point J and point K is 4√5.
Distance = √((x₂ - x₁)² + (y₂ - y₁)²)
In this case, point J has coordinates (-3, 2) and point K has coordinates (1, -6).
Applying the formula:
Distance = √((1 - (-3))² + (-6 - 2)²)
Distance = √((1 + 3)² + (-6 - 2)²)
Distance = √(4² + (-8)²)
Distance = √(16 + 64)
Distance = √80
Simplifying further:
Distance = √(16 * 5)
Distance = √16 * √5
Distance = 4√5
Therefore, the distance between point J and point K is 4√5.
If the midpoint of line segment XY is at (2, 8)
and point X is at (10, 4)
, what is the ordered pair of point Y?(1 point)
Responses
and point X is at (10, 4)
, what is the ordered pair of point Y?(1 point)
Responses
To find the ordered pair of point Y, we can use the midpoint formula:
Midpoint = ((x₁ + x₂)/2, (y₁ + y₂)/2)
In this case, the midpoint is (2, 8) and point X has coordinates (10, 4).
Applying the formula:
(2, 8) = ((10 + x)/2, (4 + y)/2)
Simplifying further:
2 = (10 + x)/2 and 8 = (4 + y)/2
To isolate x, we can multiply both sides of the first equation by 2:
4 = 10 + x
Subtracting 10 from both sides:
-6 = x
To isolate y, we can multiply both sides of the second equation by 2:
16 = 4 + y
Subtracting 4 from both sides:
12 = y
Therefore, the ordered pair of point Y is (-6, 12).
