In the line y = 0x - 10, what are the slope and y-intercept?
Answer and explanation
Correct answer: Slope 0, y-intercept -10
A line written as y = mx + b has slope m and y-intercept b. Comparing y = 0x - 10 with this form gives m = 0 and b = -10. Thus the graph is a horizontal line crossing the y-axis at (0, -10). Option A states both values correctly. Option B interchanges the coefficient and constant, while options C and D incorrectly change the signs. The zero coefficient means there is no rise as x changes.
