Aclimber starts to descend from 533 feet above sea level and keeps going until she reaches 10 feet below sea level how many feet did she descend

It's distance covered that's important here.  533 feet down to sea level is just that: 533 feet; if the climber continues descending, we add that additional descent to 533 ft, obtaining a total descent of 543 ft.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
