If (x, y) is a solution to the system of equations shown below, what is the product of the y-coordinates of the solutions? x^2+4y^2=40 x+2y=8

The product of the y-coordinates of the solutions is equal to 3

Step-by-step explanation:

we have

-----> equation A

------> equation B

Solve by graphing

Remember that the solutions of the system of equations are the intersection point both graphs

using a graphing tool

The solutions are the points (2,3) and (6,1)

see the attached figure

The y-coordinates of the solutions are 3 and 1

therefore

The product of the y-coordinates of the solutions is equal to

(3)(1)=3

answer: 2 and 1
