In the line y = 0x + 3, what are the slope and y-intercept?
Answer and explanation
Correct answer: Slope 0, y-intercept 3
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In y = 0x + 3, the coefficient of x is m = 0 and the constant is b = 3. Therefore the line is horizontal and crosses the y-axis at (0, 3). Option A is correct. Options B and C exchange the two quantities, and option D changes the positive intercept to a negative one.
