Starting from the same
location, one bird flew 12
miles west and another
bird flew 4 miles north.
Find the direct distance
between the birds.

The direct distance between the birds is 12.64 miles.  

Step-by-step explanation:

We have, one bird flew 12  miles west and another  bird flew 4 miles north.  It is required to find the direct distance  between the birds. It means we need to find the resultant of two displacement. It can be given by :

So, the direct distance between the birds is 12.64 miles.

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.
