Answer:
c
Step-by-step explanation:
To do this, we're going to use the order of operations (PEMDAS):
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
First let's do parentheses, there isn't anythig in parentheses we need to simplify, so we can skip this step.
Next let's look for exponents. I see we have a
so let's replace that with
:

Now let's look for multiplcation. We know that things that are right next to eachother in parentheses represent multiplcation, so let's simply this more:



And now we're left with a simple problem we know how to solve.

Answer: y-6 = 0.5 (x-8)
Step-by-step explanation:
y − y1 = m(x − x1)
The equation is useful when we know:
one point on the line: (x1,y1)
and the slope of the line: m,
and want to find other points on the line.
Have a play with it first (move the point, try different slopes):
