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.
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
