Answer:

-1/8

Step-by-step explanation:

y = 8x+5

This is in the form y= mx+b where m is the slope

The slope of the line is 8

We want a line that is perpendicular

Perpendicular lines have slopes that are negative reciprocals

m perpendicular is -1/8

fichoh

The slope of the line perpendicular to the line y = 8x + 5 is

-1/8

The equation gives is a linear line which is written in the form y = bx + c

  • b = slope of the line

Comparing the equation given with the general form of the equation, the slope is 8

Since the line is perpendicular, the the slope is taken to be the negative reciprocal of b ;

Reciprocal of a number = 1 / number

Hence, reciprocal of 8 = 1/8

Negative 1/8 = - 1/8

Therefore, the required slope value is - 1/8
