What is the slope of the equation y = 6x + 3?
3
6
9
12
The correct answer is: 6
The slope of an equation in the form y = mx + b is equal to the coefficient of x, which in this case is 6. Option A, 3, refers to the y-intercept and is not the slope. Option C, 9, is multiplying x by 1.5, which would not give the same function as the given equation. Option D, 12, is twice the slope, which would not give the same function as the given equation. Therefore, option B, 6, is the correct answer.
