The general equation of a straight line is: = + . We can tell 2 things about the straight line from the equation: = + The gradient of the line the -intercept (where it crosses the -axis) Example: Look at the straight line equation: = + . We know (just by looking) that...
How to Find the Slope of a Perpendicular Line Perpendicular Line Slope Examples Lesson Summary Slope of a Line Formula Slope, also called the gradient or rate of change, is a value that describes how steep a line is and the direction of the line. Slope is used in algebra to find the an...
The previous methods work nicely except for a vertical line:In this case the gradient is undefined (as we cannot divide by 0):m = yA − yBxA − xB = 4 − 12 − 2 = 30 = undefinedSo just rely on the fact that:a vertical line is parallel to another vertical line. a ...
