Slope of a line is the measure of the steepness and the direction of the line. It can be calculated using any two points lying on the line. Learn formula and method to find slope of line.
What is the slope of this horizontal straight line? Solution: We need two points that a line passes through in order to find the slope of the line. The two points are A and B with coordinates $(-4,4), (4,4)$ respectively.
In this article, we are going to discuss what a slope is, slope formula for parallel lines, 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.
Questions with Solutions. Find the slope of the line passing through the pairs of points and describe the line as rising, falling, horizontal or vertical. Since the slope is positive, the line rises as x increases. Since the slope is negative, the line falls as x increases.
Slope of a line, slope of line using the graph (rise and run), using the slope formula, negative slope, y-intercept, examples and step by step solutions
This page consists of printable exercises like introduction to slopes such as identifying the type and counting the rise and run; finding the slope using ratio method, slope-intercept formula and two-point formula; drawing lines through coordinates and much more!
