So this is how you do it enjoy
Answer:
B
Step-by-step explanation:
y is first so, 8,1 6,2 4,3 2,4 0,5
Equation in point-slope form is 
Option C is correct.
Step-by-step explanation:
We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5
The formula used for point-slope form is:

We are given slope m = 4/5
Point (-7,9) where x₁ = -7 and y₁ = 9
Putting values in the formula:

So, equation in point-slope form is 
Option C is correct.

Answer:

✑ Question :
- Is ( 11 , 9 ) , ( 11 , 5 ) , ( 9 , 3 ) a function ?
No , it's not a function.
✎ Reason :
This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.
♨ Explore about function :
↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.
