Best ResponseYou've already chosen the best response.0did you type the question wrong? it looks like it's going for a perpendicular relationship, but that would be a negative reciprocal if not, the second line is 9 times as steep (slope wise) as the first... and they would intercept at 1/3x + 10 = 3x + 2/3 x + 30 = 9x + 2 8x = 28 x = 7/2 y = 335 / 30 = 67 / 6 intersect at (7/2, 67/6)

Best ResponseYou've already chosen the best response.0the definition of perpendicular lines requires that the slopes of the lines have to be negative reciprocals. Negative reciprocals means that it's negative and inversed (1/x) so in your example y=1/3x+10 and 3y=9x+2 change both to y = mb + c y=1/3x+10 y=3x+2/3 so the slopes are 1/3 and 3 if you take the negative reciprocal of 1/3 would be \[\frac{1}{\frac{1}{3}}* 1\] which would equal 3 Since they are negative reciprocals, they are perpendicular it's a rule memorize it just like how parallel lines have the same slope, it's the same idea perpendicular lines are negative reciprocals cheers ^_^
