So a function would have no equation is just put numbers that don’t creat an equation like 5,3 in one column and another one with 8,2
Answer:

Step-by-step explanation:
Slope intercept form :
y = mx + b
m is the slope
b is the y-intercept
Let's look for m, use the formula
to determine it.


Now find b, we simply need to plug in one of our coordinates to get our answer.
(12, -9)

Solve for b :
-9 = -6 + b
-3 = b
b = -3
Our slope intercept is :
