1. Four submarines are exploring an undersea trench. The depth of
each submarine is shown. Use absolute values to represent the
distance of each submarine from sea level. Which submarine
is closest to sea level?

1/5^2 = 7.56/45

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.

50-38=12
