Assume your points are (x1, y1) and (x2, y2). The slope of a line is its rise (the change in y-coordinates) over its run (the change in x-coordinates). So to find the slope of the line, you substitute the correct values into the formula (y2 - y1) / (x2 - x1).
(0,5).
slope = change_in_y/change_in_x = (-1 - 2)/(8 - 5) = -3/3 = -1

Not always. For example, try to find the slope of the line that passes through the points (3, 4) and (2, 3).
It is a straight line with no slope with a 'y' intercept of 2
Slope, m, equals (y2-y1)/(x2-x1). Slope is (8-2)/(8-2) or 1.
Another set of points are needed to find the slope.
Slope, m, equals (y2-y1)/(x2-x1). Slope is (0-(-1))/(0-(-1)) or 1/1 or 1.
It's not possible because the given points would be a vertical line parallel to the y axis
The slope of a line can be found using the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. For the line that passes through the points A(-2, -1) and B(3, 5), we have: m = (y2 - y1) / (x2 - x1) = (5 - (-1)) / (3 - (-2)) = 6 / 5 = 1.2 So the slope of the line that passes through the points A(-2, -1) and B(3, 5) is 1.2.
