Question

4) IfR(1,-1) and S(-2,5) then find the slope of line RS​

Answer 1

Answer:

The slope of the line RS is -2.

Step-by-step explanation:

The slope of a line on the plane connecting two points $(x,y)$ and $(a,b)$ is,

$slope = \dfrac{b-y}{a-x}$

Given two points on the plane R(1,-1) and S(-2,5). We need to find the slope of the line RS. Using the above formula,

$Slope = \dfrac{5-(-1)}{-2-1}= \dfrac{5+1}{-3} =\dfrac{6}{-3} = -2$

So the slope of the line is -2.
