Jul 03, 2010 · Since parallel lines have the same slope and this is a horizontal line, then the slope is 0. Slope of the perpendicular line: Since vertical and horizontal lines are perpendicular to each other and this is a horizontal line, then the slope of the perpendicular line in this case would be the slope of a vertical line which would be undefined. Feb 20, 2010 · The slope of the parallel line is 2/3 and the slope of the perpendicular line is -3/2. Example 3 : Find the slope of the line that is a) parallel and b) perpendicular to the line .
The two slopes m1 and m2 are not equal and their products is not equal to -1. Hence the two lines are neither parallel nor perpendicular. b. m1 = ( 1 - 3 ) / ( 3 - 0 ) = -2 / 3 m2 = ( -5 - 4 ) / ( -7 - (-1) ) = -9 / -6 = 3/2 The product of the two slopes m1*m2 = (-2 / 3)(3 / 2) = -1, the two lines are perpendicular. Example: Find the equation of the line that is: parallel to y = 2x + 1 ; and passes though the point (5,4) The slope of y=2x+1 is: 2. The parallel line needs to have the same slope of 2.
