The slope of a line is the measure of the steepness and the direction of the line. Finding the slope of lines in a coordinate plane can help in predicting whether the lines are parallel, perpendicular, or none without actually using a compass. The slope of any line can be calculated using...

, perpendicular lines, slope for collinearity with many solved examples in detail. what is a slope? in mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate. the net change in y-coordinate is represented by Δy and the net change in...
Parallel lines have equal slopes. If you find the slope of one line, you don't have to use the formula for the other line. They will be the same. This can save you some time and effort. Perpendicular lines have negative reciprocal slopes. If two lines cross at a right angle, you ca...

Find the slope of the lines x=ax=a and y=by=b Recognize that horizontal lines have slope = 0 Recognize that vertical lines have slopes that are undefined Identify slopes of parallel and perpendicular lines Given a line, identify the slope of another line that is parallel to it Given a ...
Parallel and perpendicular lines2nd level:The point-slope formulaThe two-point-formulaIN THE PREVIOUS LESSON, we took up the equation of a straight line. Sketching the graph of the equation of a line is a basic skill.Consider this straight line. The (x, y) coördinates at B have changed...
Draw a vertical line x = 1 to form ABC. We will be using the Distance Formula to express the sides of ABC, and then we will attempt to show that the sides satisfy the Pythagorean Theorem proving ABC to be a right triangle (making the lines perpendicular). Proof: 1. m1 =...
