6. Neil gets in an elevator at the 30th floor, and it begins to move downward at a speed of 8 feet per second. After 12 seconds, the elevator is 240 feet above the ground.

A: Let y = the height in feet of the elevator x seconds after Neil got in.
Write an equation to show the relationship between x
and y.

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.
