Question

IN NEED OF HELP ASAP!!!

Answer 1

Answer:

D

Step-by-step explanation:

If you find the slope, it is -4. Wheb x is 0, y is 18, so the y intercept is 18

Therefore the equation is y=-4x+18, which is not linear.

Answer 2

Answer is D. The data does represent a linear function as it can be represented in the form:

$y = mx + b$
at x=0 y=18 so our value for b is 18.

the slope is the rate of change. we see that for each increment x increases 1 our y value decreases by 4. Therefore m = -4

Putting it all together:
$y = - 4x + 18$
Proving D is correct and that this is linear.
