Question 10 (Multiple Choice Worth 1 points)

Solve the following system of equations by graphing.

x + 2y = 4
2x + 4y = 8

What is the solution?

(4,2)

no solution

infinite solutions

none of the above

Answer 1

take the first equation
solutions exist when y=0 so substitute
gives x=4
so we have an answer x=4, y=0 giving solution (4,0)
So there is one solution. Since they are both along the same straight line just different segments, as they are parallel, there is only one solution and it is not any of the options given.
Answer none of the above.
