Answer:

Step-by-step explanation:
As you can observe in the image attached, the line that best fits passes through point B and C. That means we can use those point to find the slope of such line.

Where
and 

So, the slope of the line that best fits is -11, approximately.
Now, we use the point-slope formula to find the equation.

Therefore, the line that best fits is
approximately.
Remember, when we estimate a line for some data on a scatterplot, we are calculating an approximation, that's why we also said "approximately", because the line is an approximation where the majority of point meet.
2(x + 3) = x - 4
distribute
2x + 6 = x - 4
either subtract 6 from both sides or add 4. i will be subtracting 6.
2x = x - 10
subtract x from both sides
x = -10
Answer:
2x - 6y = 18
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
x = 2y + 6
Multiply through by 3 to clear the fraction
2x = 6y + 18 ( subtract 6y from both sides )
2x - 6y = 18 ← in standard form
