Answer:
<h2>

</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the slope of the perpendicular line we must first find the slope of the original line
The original line is
2x + 3y = 9
3y = - 2x + 9

Since the lines are perpendicular to each other the slope of the perpendicular line is the negative inverse of the original line
So the slope of the perpendicular line is

You just need pythagorean theorem c=a2+b2=72+42≈8.06226
A reflection. That is because when reflecting an image you use a line of reflection, so basically a mirror image has been created so the orientation doesn't change.
