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.

What and the slope of y-9-2(x-8)?

If you mean: y -9 = -2(x -8) then y = -2x +25 whereas -2 is the slope and 25 is the y intercept

What is the slope of a staircase when the measurement is 9 inch treads and 8 1.2 inch rises?

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.

How do you find the equation of a line that is perpendicular to y equals 9 divided by 8x plus 1 and passes through the point 18 -8?

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.


What is the slope of points -6 3 and points 2 9?

Points do not have a slope but a straight line joining them does: (9-3)/(2- -6) = 6/8 = 3/4 or 0.75
