In this image, point a is the center of the circle. which two line segments must be equal in length? a)`bar(ah)`and`bar(bc)`b)`bar(hi)` and `bar(bc)`c)`bar(ef)`and `bar(hi)d)`bar(ef)`and `bar(ai)`

Choice C) Segment EF and segment HI are the same length

Why is this the answer? Because these two segments are diameters of the same circle. All diameters of a given circle are the same length. A diameter is a segment that goes through the center of the circle and both endpoints are on the edge of the circle itself.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
