Question

Which system has no solution?

A. y = - 3x + 8
6x + 2y = -4.5
B. y = 9x + 6.25
- 18 + 2y = 12.5
C. y = 4.5x -5
- 3x + 2y = 6
D. y = 3x + 9
x = 8y = 12.3

Answer 1

A

Explanation:

When you graph each equation, all of the answers except for A have an intersection between the 2 lines. In answer A, the lines are parallel, meaning they will never intersect.
