yyyh
Answer:
They have the same slope but different y-intercepts, so they have no solution.
Step-by-step explanation:
The slope is the coefficient of x. In both cases, it is -2, so the lines have the same slope. (This eliminates the last two answer choices.)
The added constants are different for the two lines, so they have different y-intercepts. This means the lines are parallel and do not intersect.
A "solution" to the system of equations is a point (x, y) that satisfies both equations. Since the lines have no points in common, there are no solutions. (matches the first answer choice)
