The similarities between constructing a perpendicular line through a point on a line and constructing a perpendicular through a point off a line include:
- Both methods involve making a 90-degree angle between two lines.
- The methods determine a point equidistant from two equidistant points on the line.
<h3>What are perpendicular lines?</h3>
Perpendicular lines are defined as two lines that meet or intersect each other at right angles.
In this case, both methods involve making a 90-degree angle between two lines and the methods determine a point equidistant from two equidistant points on the line.

The solution to the system of equations is (3, 2)
<h3>System of equation</h3>
Give the system of equation below
y = -x + 5
y=x-1
Equate both expression
-x+5 =x - 1
Equate
-x - x = -1 - 5
-2x = -6
x = 3
Since y = x - 1
y = 3 - 1
y = 2
Hence the solution to the system of equations is (3, 2)

First thing you would do is distribute the negative on the outside of the parentheses to the inside terms:
9x - 5x + 7 = 39
Now, combine like terms:
4x + 7 = 39
Subtract 7 from both sides to get variables on one side of the equal sign and constants on the other:
4x = 39 - 7
4x = 32
Divide both sides by 4 to isolate the variable x.
x = 32 / 4
x = 8
