The equation of the median in standard form is; 9y - 38x = 179.

<h3>What is the equation of the media in standard form?</h3>

It follows from the task content that the point D is the midpoint of segment BC; Hence, the coordinates of point D given the coordinates of B and C above are given as; D(-13, -35).

The equation of the median which is the line joining points A and D is therefore determined as follows;

Slope = (-35-3)/(-13-(-4)) = 38/9

38/9 = (y-3)/(x+4)

9y -27 = 38x + 152

9y - 38x = 179.

What are the coordinates of point B?
zaharov [31]

Point a is at (-2,4) => (x1,y1)

Midpoint is (2.5, 3.5) => (a,b)

Point B is (x2, y2)

To find midpoint we use formula

(a=\frac{x_1+x_2}{2} , b= \frac{y_1+y_2}{2})

a= 2.5, b= 3.5, x1= -2  and y1= 4

Plug in all the values and findout x2, y2

(2.5=\frac{-2+x_2}{2} , 3.5= \frac{4+y_2}{2})

multiply 2 on both sides to remove fraction

(5 = -2+x2 , 7 = 4+ y2)

5 = -2+x2, so x2= 7

7 = 4+ y2, so y2= 3

The point B is ( 7, 3)

You live on a triangular piece of land with a base of 121 yards and
morpeh [17]

The area of triangular piece of land in acres is 1 acre.

Further Explanation:

In order to find the area of the triangular piece of land in acres we have to find the area in yards

<u>Given:</u>

Base = 121 yards

Height = 80 yards

Area = \frac{1}{2} * base * height\\ = 0.5 * 121 *80\\=4840\ square\ yards\\Square\ Yards\ in\ one\ acre=4840\ square\ yards\\So,\\Area\ in\ acres = \frac{4840}{4840} \\= 1\ acre

So, the area of triangular piece of land in acres is 1 acre.

Keywords: Area of triangle, conversion from yards to acre
