**7.2 Parallel and Perpendicular Lines McGraw Hill Education**

Two perpendicular lines can be identified by looking at the product of their slopes (if it is equal to -1, the lines are perpendicular). The equation of the red (known) line is y=2x+1. We also know that the perpendicular line passes through the point (2,-1).... 7 worksheets that show the relationship between the gradients of perpendicular lines. Excellent revision/extension for work on gradients. The answers are included. Find the gradient of lines on grids and then draw lines perpendicular to them. Us...

18/03/2010 · the gradient of the straight line perpendicular to the line with x intercept 3 and y intercept 2 is equal to 3/2. Hope I helped You. I'm Waiting for 10 points!!!... 7.2 Parallel and Perpendicular Lines 7.2 OBJECTIVES 1. Determine whether two lines are parallel 2. Determine whether two lines are perpendicular 3. Find the slope of a line perpendicular to a given line For most inexperienced drivers, the most difﬁcult driving maneuver to master is parallel parking. What is parallel parking? It is the act of backing into a curbside space so that the car’s

"We know that the product of the gradients of two perpendicular lines is -1." There's your error- we DON'T know that. What we know is that "if two perpendicular lines have FINITE slope then the product of their slopes is -1. That statement does not even make sense if one of the lines does not have a slope (does not have a finite slope)..... If the slope of a line is m, then the slope of a line perpendicular to it is -1/m. So, m * -1/m = -1. This number is always negative because: a negative times a positive is always negative.

**Quiz & Worksheet Finding the Slope of a Perpendicular**

The two lines are perpendicular if the product of their slopes is -1 (i.e. m1 x m2 = -1) or one has a slope of 0 (a horizontal line) and the other has an undefined slope (a vertical line) i.e m1 = 0 and m2 = ∞ or m1 = ∞ and m2 = 0. From the above, notice that given two perpendicular lines and the slope of one line, you can always find the other slope from the relationship. i.e. Slope in... If the slope of a line is m, then the slope of a line perpendicular to it is -1/m. So, m * -1/m = -1. This number is always negative because: a negative times a positive is always negative.
