the slope is the coefficient of friction. look at the equation of the graph as apply it to any of the friction problems your teacher gave you.
Acceleration
It means that the maximum force of friction is greater than the weight of the object.
Assuming position is on the y axis and time is on the x axis, a positive slope means the position has increased over time.
If the distance is on the y axis and time is on the x axis, a zero slope means that distance isn't changing over time.
No. A negative slope means that the object is slowing down. If the object were not moving, then its velocity would be zero. The graph would be a straight horizontal line that just lays there on the time axis.
If you mean: y = -3x then the slope is -3 and there is no y intercept
no
That slope is the 'speed' of the motion. If the slope is changing, then the speed is changing. That's 'accelerated' motion. (It doesn't matter whether the speed is growing or shrinking. It's still 'accelerated' motion. 'Acceleration' does NOT mean 'speeding up'.)

slope of best fit gives mean value?
It means a slow speed.
By grid, do you mean graph? Because a graph can have problems dealing with slope, x and y intercepts, lines, etc.
it means that the object is gradually getting faster
I am assuming the you are talking about the graph of the derivative. The graph of the derivative of F(x) is the graph such that, for any x, the value of x on the graph of the derivative of F(x) is the slope at point x in F(x).
Do you mean y = -8x+20 Then if so the perpendicular slope is positive 1/8.
If you mean: 3x-2y = 6 then y = 1.5x-3 whereas the slope is 1.5 and the y intercept is -3
