d. the graph is decreasing
Please select the best answer from the choices provided

The coordinates of C(a,b).

The length of AC diagonal is equal to

The length of BD diagonal is equal to .

Therefore, AC diagonal is congruent to BD diagonal.

Step-by-step explanation:

Given

ABCD is a rectangle.

AB=CD and BC=AD

The coordinates of rectangle ABCD are A(0,0),B(a,0),C(a,b) and D(0,b).

Distance between two points and is given by the formula

=

The distance between two points A (0,0) and C(a,b)

AC=

AC=

The length of AC diagonal is equal to .

Distance between the points B(a,0) and D(0,b)

BD=

BD=

The length of BD diagonal is equal to .

The diagonals of the rectangle have the same length.

Therefore, AC diagonal is congruent to BD diagonal.

Hence proved.
