D. Perform the indicated operation showing steps and simplify completely. Be sure to include the domain if there is a variable in the denominator.

10/63

Step-by-step explanation:

no common factors between 2 & 9

no common factors between 5 & 7

thus no simplification at the end

5*2 / 7*9 = 10/63

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.
