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...
To prove thecollinearityof three points, say A, B, and C, we can apply the slope formula. The slope of lines AB and BC should be equal for the three given points to becollinear points. The slope can be calculated using the coordinates of two points using the formula, m = (y2- y1...
