Answer:

(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)
