What is the slope of a line that is perpendicular to the line y = 8x + 5? −8 8

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

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

-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

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
