In order to calculate the slope, you need two points, each with two coordinates. That makes four numbers in all. There are only two in the question.

If you mean: y -9 = -2(x -8) then y = -2x +25 whereas the slope is -2 and the y intercept is 25
If you mean points of (6, 9) and (7, 1) then the slope of the line is -8
If you mean points of (6, 9) and (7, 1) then the slope of the line is -8
The slope is 8-1/2 divided by 9 = 0.9444...(rounded, repeating)The angle of the slope is whatever angle has a tangent of (8-1/2)/9 .That angle is 43.36 degrees. (rounded)That makes sense, because we know that if the tread and riser were equal,then the angle would be 45 degrees.
Points: (-6, 4) and (3, -4) Slope: -8/9
