Two numbers have a sum of 50 if one number is p, express the other number in terms of p.

the other number is 50 - p

Consider a numeric example

2 numbers sum to 5 , one of the numbers is 3 what is the other ?

Obviously 2 , that is 5 - 3 = 2 gives the number

In the same way the number here is p and 50 - p is the other number

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.
