Question

Find the slope of given line with given co-ordinates (x1,y1)= (9,1) and (x2,y2)=(-3,-7).

Answer 1

Given co-ordinates of the line (x1,y1)=(9,1).

                                                     (x2,y2)=(-3,-7).

Since we know that to find slope of line we have formula that is 

                                          m=(y2-y1)/(x2-x1)

               Putting the values of x1 , x2 , y1 and y2 we get 

                                          m=(-7-1)/(-3-9)

                                          m=-8/-12

                                          m=2/3.

                            Hence slope of the line is 2/3.

 

The slope of the given line with given co-ordinates is 2/3.
