A line contains points (4, 2) and (0, 4). Another line graphed in the same coordinate plane contains points (4, 3) and (5, 3). Based on the slopes of these lines, are they parallel, perpendicular or neither?

Best ResponseYou've already chosen the best response.1Inverse slope means they are perpendicular. For Example If a line has slope 3 and other has 1/3 then these two lines are perpendicular.

Best ResponseYou've already chosen the best response.1Yes if the slopes of both the lines are same then lines are parallel.

Best ResponseYou've already chosen the best response.0You have to find the slope of both lines, do you know how to do that?

Best ResponseYou've already chosen the best response.13/2 and 2/3. 2/3 is negative reciprocal of 3/2.So Lines are perpendicular.

Best ResponseYou've already chosen the best response.1how 2/4 and 1 lvasquev462? when there is a formula to find slope which is: y2y1/x2x1. So 42/0(4)=6/4=3/2

Best ResponseYou've already chosen the best response.1Similarly find the slope of second equation.Which I got as 2/3. So (m1)(m2)=1.Then lines are perpendicular. where m1=slope of first equation and m2=slope of second equation.

Best ResponseYou've already chosen the best response.1You remember formula (m1)(m2)=1 to check either lines are perpendicular or not.ok
