x – 4 = 12.5 can be written in words as: The difference of a number and x. The sum of a number and 4 is 12.5. x subtracted from 4 is equal to 12.5. A number decreased by 4 is the same as 12.5.

Step-by-step explanation:

explanation:

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.
