Can I just multiply by -1 or is it a negative reciprocal?
Whats the gradient of a line perpendicular to a line with gradient -3/2?

The product of the slopes of perpendicular lines is -1.
So,
-3/2 * s = -1
s = 2/3 is the slope of the perpend line.
To check:
(-3/2)(2/3) = -1

Yes, you can multiply the slope by -1 to get the slope of the perpendicular line, with two exceptions.
If you have a line with slope 0, it is a horizontal line. The perpendicular line will be vertical and have a slope that is undefined.
The other exception is a vertical line, which has an undefined slope. The perpendicular line will be horizontal and have a slope of 0.

The slope of a line perpendicular would be the negative reciprocal.

the gradients of perpendicular lines will be negative inverse of the gradient of the givenn line
si 2/3

negative perpindicular. is slope=-3/2, the slope of the perpindicular is
-(-2/3)=2/3
