Week 6 concept check The way to tell if two different lines are perpendicular is to compare their slopes. If the slopes of the two lines are negative reciprocals of one another, they are perpendicular lines. To say it in another way is, if you multiply the slopes of perpendicular lines, the result is -1. However, there is an exception to the rule. If a line has a slope of 0, the perpendicular line

Unformatted text preview: will have an undefined slope and vice versa. Perpendicular lines are lines the intersect at right angles and the product of their slopes are equal to -1. If two lines are represented by equations y, =m, x, +c & y^2 =m^2x^2+c then m, &m^2 represent their slopes, & if the two lines are perpendicular then m^1m^2=1. For example, 3y+2x=4 & 6x-4y=-5 are perpendicular lines....
