300 feet above sea level??

300

Step-by-step explanation:

if it is 300 feet ABOVE sea level, then it is a positive answer.

you would want to look for the words 'above' or 'below' if it is talking about sea level.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
