Question

Find the slope of line passing through the two points, (1, -4) and (5, -8).

Answer 1

Answer:

m=-1

Step-by-step explanation:

So our equation to find the slope is:

       y₂-y₁

m=   -------

       x₂-x₁

(1,-4) is our first coordinate pair, which means that we will put them like this:

1=x₁

-4=y₁

(5,-8) is our second coordinate pair, which means that we will put them like this:

5=x₂

-8=y₂

We can substitute these numbers into the original equation:

     -8-(-4)

m= ---------

       5-1

Then we can simplify::

-8+4     -4

------- = ---- =  -1

 4         4

m=-1

Answer 2

Answer: y= -1x+b, or -x+b

Step-by-step explanation:

The slope is 1 because you have to plug in the formula, y2-y1/x2-x1.  -8-(-4)/5-1. This is equal to -4/4, which is -1.
