Answer with explanation:

Given: A kite U V W X

To Prove: Diagonals of kite U V W X, that is ,U W and V X are Perpendicular.

Proof:

Slope between two points having position vector or coordinates ,A(x_{1},y_{1}) {\text{and}} B(x_{2},y_{2}) is given by:

               =\frac{\text{Difference in y coordinates}}{\text{Difference in x coordinates}}\\\\=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Step 1:

Determine the slope of XV. Suppose position vector of point X is (a,b) and Position vector of point V is (p,q).

The slope of XV is

        m_{1}=\frac{q-b}{p-a}

Step 2:

Determine the slope of UW. Suppose position vector of point U is (m,n) and Position vector of point W is (s,t).

The slope of U W is :

 m_{2}=\frac{t-n}{s-m}

Step 3: The slopes of the diagonals are, m_{1},m_{2}

Also, m_{1}\times m_{2}=-1

→→Showing that,The diagonals of kite UVWX are perpendicular to each other.

Writing equations in standard form:
d1i1m1o1n [39]
You have already done half of it. Now substitute for x1 = 4 and y = 5
y - 5 = 6/7(x - 4)
Multiply everything by 7 to remove fractions
7y - 35 = 6(x - 4)
7y - 35 = 6x - 24
-6x + 7y = -24 + 35
-6x + 7y = 11

Some people prefer a positive number in front of x so multiply by -1
6x - 7y = -11

You can check the answer by testing it works for both of the original points
6x4 - 7x5 = 24 - 35 = -11 true
6x-3 - 7x-1 = -18 - -7 = -11 true
