When driving down a mountain road, you notice warning signs indicating that it is a "8% grade." This means that the slope of the
road is -8/100. Approximate the amount of horizontal change in your position if you note from elevation markers that you have
descended 2000 feet vertically. (Round your answer to one decimal place.)

Step-by-step explanation:

the slope is (y change / x change).

since we have descended 2000 ft vertically (down, so it is a negative change), that is the y change (the y axis goes up and down).

now we need to find the horizontal x change (left or right).

-2000 / x change = -8 / 100

-2000 × 100 = x change × -8

-200000 = -8 × x change

x change = -200000 / -8 = 25000 ft

the horizontal change was 25,000 ft.
