Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).

snow_lady [41]

Answer:

( $\frac{1}{2}$ , $\frac{-1}{2}$ )

Step-by-step explanation:

Use the midpoint formula to solve.

1) Given 2 points: ( $x_{1}$ , $y_1$ ) and ( $x_2$ , $y_2$ )

The midpoint formula would be ( $\frac{x_1+x_2}{2}$ , $\frac{y_1+y_2}{2}$ ).

2) Based on this, we can easily find the midpoint of AB.

-3 would be $x_1\\$
-5 would be $y_1$
4 would be $x_2$
the next 4 would be $y_2$

3) With this information, we can solve for the midpoint.

( $\frac{-3+4}{2}$ , $\frac{-5+4}{2}$ ) --> ( $\frac{1}{2}$ , $\frac{-1}{2}$ ) --> This is your answer.

ABDE is a rectangle on coordinate axes, the sides of the rectangle are parallel to the axes,

Hitman42 [59]

The coordinates of B and D are the location of the vertices B and D in the rectangle

The coordinates of B and D are (55, 30) and (55, 14)

<h3>How to determine the coordinates of B and D?</h3>

From the figure of the rectangle, we have:

A = (25,30)

C = (40, 22)

Point B has the same y-coordinate as point A

So, we have:

B = (x, 30)

The x-coordinate is then calculated as:

Bx = 2Cx - Ax

This gives

Bx = 2*40 - 25

Bx = 55

So, the coordinates of B are:

B = (55, 30)

Point D has the same x-coordinate as point B

So, we have:

D = (55, y)

The y-coordinate is then calculated as:

Dy = Cy - (By - Cy)

This gives

Dy = 22 - (30 - 22)

Dy = 14

So, the coordinates of B are:

D = (55, 14)

Hence, the coordinates of B and D are (55, 30) and (55, 14)
