Write the equation of the line with the given slope, m, and y-intercept, (0, b).
-m = 0; b = -3
A)y = -3
B)y = x - 3
C)x = -3
D)x = y - 3

Quizplus · Accepted Answer

When the slope is 0, the line is horizontal and only intersects the y-axis at the y-intercept, which is (0, b). Therefore, the equation of the line is y = b, and in this case, y = -3. When the slope is 0, the line is horizontal and parallel to the x-axis. Therefore, the y-coordinate of every point on the line is the same, which is b in this case. So the equation of the line is y = -3.
