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
Points: (9, 6) and (3, 8) Slope: -1/3
Points: (9, 6) and (3, 8) Slope: -1/3
If you mean: y -9 = -2(x -8) then y = -2x +25 whereas -2 is the slope and 25 is the y intercept
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
(4 - 8) / (9 - 5) = -1 or -1/1
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
The "point slope" formula would be used. This is Y-Y1=m(X-X1) where Y1 and X1 are points the line passes through. M is the slope, so to find the slope of a line perpendicular, take it's opposite reciprocal which would be -8x/9. So Y-(-8)=-8/9(X-18) distribute -8/9 into X-18 and add the 8 on the left side of the = to get the slope intercept form.
Points do not have a slope but a straight line joining them does: (9-3)/(2- -6) = 6/8 = 3/4 or 0.75
