|r + 3| = 7

r + 3 = -7 or r + 3 = 7

r + 3 = -7;
r = -7 - 3;
r = -10;

r + 3 = 7;
r = 7 - 3;
r = 4;

r = {-10, 4}

The graph should show a steep increase when the hiker climbs up the bank, a flat line when the hiker rests, a gentle increase when the hiker walks up the hill, and another flat line when the hiker reaches the plateau.
