Sammy starts her hike at 230 feet below sea level. When she reaches the end of the hike, she is still below sea level at −138 feet. What was the change in elevation from the beginning of Sammy's hike to the end of the hike?

92 feet

Step-by-step explanation:

230 - 138 is 92

Since it is both under sea level, they are both negative numbers and it’s going up.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
