what's the slope of the line (9,2);(3,-1) ?
(-1 -2)/(3-9) = -3/-6 = 1/2
thanx a bunch drwls! i appreciate it! <3
To find the slope of a line given two points, you can use the formula:
slope (m) = (y2 - y1) / (x2 - x1)
In this case, the coordinates of the first point are (x1, y1) = (9, 2) and the coordinates of the second point are (x2, y2) = (3, -1).
Substituting these values into the formula, we get:
slope (m) = (-1 - 2) / (3 - 9)
Simplifying further, we have:
slope (m) = (-3) / (-6)
Finally, simplifying the fraction gives us:
slope (m) = 1/2
Therefore, the slope of the line passing through the points (9, 2) and (3, -1) is 1/2.
