1)use the given condition to find an equation in slope-intercept from of each of the nonvertical lines Parrlel to 3x-4y=-54;passing through (-6,8) 2)Determine wheather the pair of lines is paralled,prepeniduclar or neither 3x-6y=-12 , 18x+9y=-12 Solution (1) y=3x/4-27/2 slope of the line is 3/4 equation is y-8 = 3(x+6)/4 4y -32 = 3x + 18 4y-3x = 50 (2) m1 : y = x/2 + 2 m1 = 1/2 m2 : y = -2 - 4/3 m2 = -2 m1 * m2 = 1 Hence line are perpendicular.
