Points A(-4, 16) and B(-14, 0) are two points on line AB and line m has equation y=-5/8x-6. Find the slope of AB and the slope of line m. What can you determine about AB and line m? Explain your reasoning.
Slope of AB = 8/5, slope of line m = -5/8. They are perpendicular, because their slopes are negative reciprocals.
