Slope Of Parallel Lines Math
These lines are parallel and have the same slope of m 3 5.
Slope of parallel lines math. 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 the same slope are parallel. This is also the slope of the parallel line. This is true for all parallel lines.
The converse is also true. If two lines have the same slope the two lines are parallel unless they overlap. In this case the slop is. In order to determine the slope from an equation we need to make sure that it is written in the following format.
Y m x b y m x b. If the equation of a line is written in the slope intercept form then is slope and is the y intercept. When finding the slope of a parallel line the slope will be the same as the other equation given. M 4 m 4.
Have the same slope m for example observe the purple line and the green line in figure 1 below. Tap for more steps. Using the slope intercept form the slope is 4 4. Y 4x 2 y 4 x 2.
Perpendicular lines are a bit more complicated. Slope of parallel lines in coordinate geometry parallel lines have the same slope. Find the slope of a parallel line. The blue line below is the graph of the equation y 2x 3 and the black line is y 2x 4.
