Accuplacer Practice Test

The equation y = 2x represents a line with a slope of 2. This means that the other line must also have a slope of 2 to be parallel to it. In option A, the slope is 2, but the y-intercept is not the same, making the two lines not parallel. In option B, the slope is also 2, but the y-intercept is not the same. Option D has the same slope and y-intercept, but the equation is the same as option A, which we have already determined is not parallel to y = 2x. Option C, on the other hand, has the same slope and y-intercept as y = 2x, making it the only correct answer.
