Question

Line A is represented by the following equation:

x + y = 2

What is most likely the equation for line B so the set of equations has no solution? (4 points)

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

Answer 1

2x+2y=4

Explanation:

Answer 2

Line A : x + y = 2

The most likely equation for line B so that the set of equation has no solution is:

x + y = 4

====

x + y = 2
x = 2 - y

2-y + y = 4
0 = 4 - 2
0 ≠ 2

there is no value for x nor y. so, no solution.
