If I’m correct the answer is
Y=3
-7.8
The rest can be solved as rational. Negative numbers are not rational.
The distance between (-4,3,-6) and the origin is 
<h3>How to determine the distance?</h3>
The point is given as:
(x, y, z) = (-4,3,-6)
The origin is
(x, y, z) = (0,0,0)
The distance between the point and the origin is calculated as:
So, we have:
Evaluate
Hence, the distance between (-4,3,-6) and the origin is

The gradient of the perpendicular line would be the negative reciprocal of the original line. Therefore the gradient of the perpendicular line would be -2/5x.
Since we know y=mx+c, ∴y=-2/5x+c. Sub in the x and y values of the given point and we get that c=26/5.
The perpendicular equation would be y=-2/5x+26/5.
I hope I got this right.
Hey the answer is -0.2. You have to divide 10 by both sides to isolate the variable
