Slope & FormulaHor. & Vert. LinesPar. & Perp. Lines Purplemath Parallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with ...
How do we know when two lines are parallel?Their slopes are the same!The slope is the value m in the equation of a line: y = mx + bExample: 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...

Slopes of Parallel Lines:In mathematics, the slopes of parallel lines are always equal. We can use this fact to solve various math problems involving parallel lines, their equations, and their slopes.Answer and Explanation: Any equation of the form y = 2x + b, where b is any real number...
A horizontal line has a slope of zero and a vertical line has an undefined slope. These two lines are perpendicular, but the product of their slopes is not –1. Doesn’t this fact contradict the definition of perpendicular lines? No. For two perpendicular linear functions, the product of ...
Note that the slopes of the two parallel lines are always the same. For example, if the slope of the straight line in the equation y=4x+3is 4, then all lines parallel toy=4x+3have the same slope, or 4. Parallel lines have different y-intersections and have no points or angles in ...
Parallel and Perpendicular Lines Parallel and Perpendicular Lines Two lines are parallel if one can be translated, without rotation, to lie on top of the other. Two lines are perpendicular if they meet at a right angle (an angle of 90). Mathematically,..

A Cartesian plane uses gridded lines that run vertical and horizontal and create boxes that have the value of 1 as their sides. The vertical lines represent the y-axis and the horizontal represent the x-axis with regards to direction.
