Question

What is the slope of the joining the points (2,0) (-2,0)​

Answer 1

first find it by using y2-y1 by x2-x1

and then equate to dy/dx

Answer 2

Given ,

The points are (2,0) and (-2,0)

We know that , the point slope form is given by

$\large \sf \green{ \fbox {\fbox{ \pink{M = \frac{ \: y - y_{1} \: }{x - x_{1}} }}}}$

So , the slope of the line passing through (2,0) and (-2,0) is

$\sf = \frac{0 - 0}{ - 2 - 2} \\ \\ \sf = \frac{0}{ - 4} \\ \\ \sf = 0 \: \: units$

Hence , the slope is 0 units
