Answer:
y-4=-2(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-4-4)/(3-(-1))
m=-8/(3+1)
m=-8/4
m=-2
y-4=-2(x-(-1))
y-4=-2(x+1)
You would use the distance formula

Answer:
-13/4 =n
Step-by-step explanation:
-5/2 = 3/4 +n
Subtract 3/4 from each side
-5/2 - 3/4 = 3/4 +n-3/4
-5/2 -3/4 =n
Get a common denominator
-5/2 *2/2 - 3/4=n
-10/4 - 3/4 = n
-13/4 =n
