Question

4. The equation of one of the diagonals of a kite is f(x) = -½ × + 10. If the diagonals intersect at (-4, 12), what is the equation of the other diagonal in k(x) form? (Explain the choice you make for the slope.)

Answer 1

Answer: k(x) = 2x + 20

Explanation:

The diagonals of a kite will always be perpendicular.

Perpendicular slopes' product is -1, so m x m = -1.

-1/2 x 2 = -1.
