Question

The slope at point A of the graph given below is:​

Answer 1

`(RQ)/(PQ)`

Step-by-step explanation:

The slope of a graph at a point can be calculated from the tangent to the graph at that point, and it is given as

`m=(\Delta y)/(\Delta x)`

where

`\Delta y` is the increment in the y-variable

`\Delta x` is the increment in the x-variable

From the figure we see that in this case:

`\Delta y =RQ\\\Delta x = PQ`

So, the slope at point A is

`m=(RQ)/(PQ)`
