Question

The solution for a system of two linear equations is (0, 0). Which equation below could be one of the equations in the system? A. B. Y = –3x C. Y = 4x – 5 D. Y = 5 – x

Answer 1

B

Explanation:

y = -3x

Answer 2

y = -3x

Explanation:

For the equation to be a part of a system, the point (0,0) must be a part of the line. Since y = -3x is proportional meaning b = 0, its y-intercept is (0,0). This means it must cross through and include (0,0). This is a part of the system.
