-1/2

Explanation:

the product of the slope of the normal and the slope of the line

must be = -1 is they are perpendicular to one another

the line y = 2x - 3 is in the form y = mx + b

where m is the slope so the slope for this line is 2

then Slope of Normal * 2 = -1

slope of normal = -1/2

-1/2

Explanation:

Perpendicular slopes are opposite reciprocals of one another. In the equation, the slope is 2 (it's in the form y=mx+b, where m is the slope).

Opposites (negative version of a positive number and vice versa):

-3, 3

2/4, -2/4

13/9, -13/9

Reciprocals (switch the numerator and denominator):

1/2, 2

13/7, 7/13

-23, -1/23

The opposite number of 2 is -2 and the reciprocal of -2 is 1/2.
