Question

Find the slope of the straight line that passes through the following pair of points: (- 1, -5) and (4, 5).

The slope is

Answer 1

The slope of a line is "rise over run" or  "the change in y  over   the change in x"  or

 

y2 - y1

---------

x2 - x1

 

So your two points (-1,-5), this would be your (x1, y1) and 

your point (4,5) this would be your (x2, y2)

 

So y2-y1 = 5 - (-5) = 5 + 5 = 10

 

and x2-x1 = 4 - (-1) = 4 + 1 = 5

 

y2-y1               10

------- =   --------

x2-x1                5

 

 

So the slope is 10/5 = 2
