What is the slope of line m? picture--> http://static.k12.com/calms_media/media/1299000_1299500/1299411/1/a11c760dca89e9a18f19e938a970723a023fd8b8/144240.jpg A. - 1/3 B. 3 C. -3 D. 1/3
You can find the line using two points on the line. There are two given points with their coordinates. Can you write the coordinates of both points below?
(2,0) and (0,6) @mathstudent55
slope is rise to run.
Good. To find the slope using two points, first, subtract the two y-values. What do you get?
BTW, it's (0, -6). Be careful. It's hard to see the negative sign on the -6.
6
Ok. Now subtract the x-values in the same order.

Good. Now divide the difference in y by the difference in x. That is the slope of line m.
slope = (y2 - y1) / (x2 - x1) (2,0)..x1 = 2 and y1 = 0 (0,-6)...x2 = 0 and y2 = -6 now sub slope = (-6 - 0) / (0 - 2) can you finish ?

The slope of the line containing the points \((x_1, y_1) \) and \((x_2, y_2) \) is \(m = \dfrac{y_2 - y_1}{x_2 - x_1} \) The important this is that when you subtract the y- and x-coordinates, you need to do both subtractions in the same order.
Correct.
WHOOP...WHOOP...WHOOP...you got it :)
thank you guy:)
You're welcome.
