Which of the following segments is a radius of circle o?

B.  

Step-by-step explanation:

We know that the radius of a circle is a line segment which starts from the center of the circle and ends to any point on the circle.

From the given figure , it can be seen that there are three line segments in the circle which starts from center to a point on circle .

Thus, The radius of the circle with center O=

From the given options , line segment is  a radius of circle O.

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
