A "rigid motion" refers to which of the following? change in neither size nor shape
change in both size and shape
change in shape but not size
change in size but not shape

Change in neither size or shape

Step-by-step explanation:

Rigid motion changes the location or direction of the object not their size or shape

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.
