Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). Topics you'll explore include the slope and the equation of a line. Slope tells us how steep a line is. It's like measuring how quickly a hill goes up or down. We find the slope by seeing how much we go up or down (vertical change) for each step to the right …
Remember, slope is (change in y)/ (change in x). The slope of a vertical line is undefined because the change in x = 0 and dividing by 0 is undefined. Hope this helps. A line with a slope of 0 is a horizontal line. A line with an undefined slope is a vertical line.
As i understand it, the goal is not to prove that the lines are parallel, but to prove that when given two parallel lines, their slopes must be the same. While this might be obvious just by looking at … Since a vertical line has no change in x-axis, or rather, all points share the same x-value, it would have 0 for denominator, which makes the fraction, and thus the slope, undefined. Practice your knowledge of horizontal and vertical lines: Their graphical presentation, their slopes, and their equations.
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as rise over run (change in y divided by change in x). Walk through a graphical explanation of how to find the slope from two points and what it means. We can draw a line through any two points on the coordinate plane. Let's take the points (3, 2) …
