MAT/116 Response Axia College of University of Phoenix Lavora Moses Instructor: Mrs. Jenell Sargent Date: January 27, 2012 How can you determine if two lines are perpendicular? If the lines are perpendicular to each other, the product of their slopes equals -1. m1 * m2 = -1 For instance, the line y = 3x + 2 and y = - (1/3) x - 8 Slopes of y1= 3, and slope of y2 = (-1/3) Hence they are perpendicular. But how can you determine if two lines are perpendicular ? Perpendicular lines have a bit of a twist to them. Two lines are perpendicular if they cross (remember,

Unformatted text preview: any two straight lines that are NOT parallel will cross at a single point) and they form a 90 degree angle, or rather, a T-shape. For example: The x-axis and y-axis are perpendicular to each other. Mathematically, if line 1 has a slope of m1, then a perpendicular line 2 will have a slope m2= (-1/m1) that is, its slope will be the negative inverse of the first....
