Answer:
y = -2/3x - 11
Step-by-step explanation:
Steps to find the perpendicular bisector:
1) Find the midpoint of line PQ
Midpoint formula: (,
)
Midpoint of line PQ = (6, -2)
2) Find the slope of line PQ
Slope formula:
Slope of line PQ = 3/2
3) Find the negative reciprocal of the slope of PQ
To find the negative reciprocal just swap the numerator and denominator and add a negative sign. If it is already negative it will become positive.
In this case it will be -2/3
4) Write the equation of line PQ in slop-intercept form.
Slope-intercept form: y = mx + b
This is what it will look like for line PQ: y = x + b
5) Plug the points of the midpoint into the line and solve for the intercept (b)
This is what it will look like: -2 = (6) + b
-2 = 18/2 + b
-2 = 9 + b
-11 = b
6) Write the equation of the perpendicular bisector
m = the negative reciprocal of the slope of PQ = -2/3
This is what the equation will look like: y = -2/3x - 11

For this case we have the following expression:
We follow the steps below:
We subtract 4x on both sides of the equation:
We subtract 10 from both sides of the equation:
Now, we must complete squares.
When we have an equation of the form:
, if we want to complete squares we must subtract c on both sides of the equation obtaining:
The square is completed by adding to both sides of the equation:
So, we have left:
In the given expression we have:
And to complete the square we have:
Rewriting we have:
We factor the left side of the equation, that is, we look for two numbers that when added together result in -8 and when multiplied as a result 16. We have:
So, we have:
Answer:
The intermediate step is to complete squares
