Final answer:
The line that passes through the points (-1, 2) and (5, 2) is horizontal, therefore has the equation y = 2, which can be written in general form as y - 2 = 0. The correct answer is option C).
Step-by-step explanation:
To find which equation represents a line that passes through the points (-1, 2) and (5, 2), you'll first notice that both points have the same y-coordinate, which means the line is horizontal. The equation for a horizontal line has the form y = k, where k is the y-coordinate that the line passes through. In this case, since both y-coordinates are 2, the equation is y = 2, which in general form is written as y - 2 = 0. Therefore, the correct option is C) y - 2 = 0.
