Answer:
point form: (2,-1)
equation form: x=2,y=-1
Step-by-step explanation:
Answer: 83.5
Step-by-step explanation:
Answer:
k = 11
Step-by-step explanation:
Given the points are collinear then the slopes between consecutive points are equal.
Using the slope formula
m = 
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m =
=
= 
Repeat with another 2 points and equate to 
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)
m =
, then
=
( cross- multiply )
k - 1 = 10 ( add 1 to both sides )
k = 11
49,375*0.11 = 5,431.25 , then add the original salary which is 49,375 and the answer is $54,806.25
