Determine the perimeter
To do this, we calculate the distance AB, BC and AC.
Distance is calculated as:

So, we have:









So, the perimeter (P) is:

The amplitude is 3 or it could also be called 5 if your looking at the y-axis
Answer:
y=-3x-1
Step-by-step explanation:
We khow the the equation of the graph function have this form : y=mx+c
- Let f be our function
- m= (f(1)-f(-1)]/[1-(-1)]=(-4-2)/2= -3
- so y= -3x+c
- let's replace x and y by the coordinates of a khown point to calculate c
- (1, -4) ⇒ -4= -3*1+c ⇒ c= -4+3 ⇒ c= -1
- y= -3x-1
