Nettet28. apr. 2012 · Given n pairs of points, how can we get the number of pair of points that can form a line with positive slope fast? Then there are n lines, where the i-th line contains two integers xi and yi specifying the x and y-coordinates of i-th point. No two points have the same x-coordinate and no two points have the same y-coordinate.

Nettet26. okt. 2024 · A system of equations has one line with a positive slope and one line with a negative slope. Which of the following statements is true? The system is inconsistent. The system is consistent. The lines are parallel to each other. There is not enough information to know whether the system is consistent or inconsistent. NettetTo find the slope (m), you would use the rise/run formula. Or: m = (y2 - y1) / (x2 - x1) For example, let's say I have two points, (1,2) and (4,8). One point would be (x1,y1) (it … un thesaurus

Nettety=1/3x - 2. is a demonstration of the Slope-Intercept Form. Which is written, y=mx + b. the -2 is obviously b which is the y-intercept. You would graph -2 as (0,-2). You would go 3 left and 1 up. Or better known as rise/run. And you would continue to get the line, by connecting the dots. NettetThe presenter, Sal, was trying to categorize the different ways that the slope can be represented (Positive, negative or zero). Maybe, the presenter should have categorized the different ways and then left the ending of the video by categorizing a slope that was indeed steeper/more negative, compared to the blue line.

Since , this can never be achieved by positive slopes , thus we can say that two positive slope lines can never be perpendicular. We can imagine it l... unthevc
