Geo 2.8 Parallel and Perpendicular Slopes

Find the slope of each line. Write the slope as a fraction in lowest form (reduce if possible). slope of a = slope of b = Then tell if they are parallel, perpendicular, or neither. b (-3, 3) a (1, 2) (2, -2) neither a b a // b Find the slope of each line. Write the slopes as fractions (reduce if possible). slope b = slope a = Tell if these lines are parallel, perpendicular, or neither. b (-3, 1) a neither perpendicular parallel (0,-3) (1, 2) (2, 0) Tell whether the two lines are parallel perpendicular or neither by finding their slopes. neither perpendicular parallel b a (-3,-1) (-3, 1) (2, 0) (3,-2) Match the following graphs with an approximate slope value. Use capital letters. slope= -4 ? slope= 0 ? y y x x slope= undefined ? slope = ¼ ? y y x x What is the slope of a line that is perpendicularto a line with a slope of -⅓What is the slope of a line that is parallel to a line with a slope of ¾? What is the slope of a line that is perpendicularto a line with a slope of ⅝What is the slope of a line that is parallel to a line with a slope of ⅞? Find the slope of the line CD if, C=(1, -4) and D=(3, 3) Another line GH is perpendicular to this line. What is the slope of line GH? slope = Find the slope of a line parallel to a line with a slope of ⅜ slope = Find the slope of a line perpendicular to a line with slope m = - ⅜ slope = Find the slope of the line EF if, E=(0, 2) and D=(5, -3)simplify your result. The line RT is perpendicular to line ED. What is the slope of line RT? slope = slope of RT = Find the slope of the line AB if, A=(-2, -3) and D=(4, -3)simplify your result. slope = Drag the label that describes the slope of the graphs below. negative slope ? Zero slope ? positive slope ? undefined slope ? Horizontal and vertical lines are ____________________ perpendicular. sometimes always never |
