Answer:
Slope is 2
Step-by-step explanation:

Thus, the slope of the line is 2.
Answer: -2-8= -10
4+1 = 5 (the negative switches to a positive)
Your slope equals -10/5. You can look at this in a fraction for when you might use it later in point slope or slope intercept form, or you can just simplify it to -2. It might also be helpful to remember the numerator as the rise and the denominator as run, or “rise over run” if you need to graph it.
Slope = -10/5 or -2
Step-by-step explanation:
Slope, often referred to as the variable “m” can be found by solving y2-y1/x2-x1. You can do it the opposite way, though make sure the y-values are on the top.
Answer:
The measure of each angle must be = 
Step-by-step explanation:
Regular Figure:
A figure where the measure of each angle is equal , is called a regular figure.
The given n- gon has n sides and n angles.
Now, here given the n - gon is a regular n - gon.
⇒ Each angle of the n-gon is equal in measure.
Hence, the measure of each angle must be = 
It would would be 68%
