Final answer:
The line given by the equation y = -3x + 6 has a slope of -3.
Step-by-step explanation:
The slope of a line measures the steepness or incline of the line and is represented by the letter m. It is defined as the ratio of the vertical change (Δy) to the horizontal change (Δx) between any two points on the line.
The line given by the equation y = -3x + 6 has a slope of -3. In slope-intercept form (y = mx + b), the coefficient of x represents the slope. Since the coefficient of x in this equation is -3, we can conclude that the slope is -3.
