Question

formula of slope of the any graph with graph

Answer 1

To find the slope of a straight line:
Slope =y2−y1/ x2−x1


Where,
(x1,y1) and (x2,y2) are two arbitrary points on the line.

To find the slope of a tangent drawn through a point on an arbitrary curve:

Slope = dy/dx



After finding the derivative of the function w.r.t x,

substitute the co-ordinates (x,y) of the point

you want to find the slope of the tangent for.

To find the slope of the normal drawn through

a point, find the slope of the tangent at that point and then take the negative reciprocal to get the slope of the normal.

Slope = −dx/dy
