Maya dropped her keys down a storm drain. Her hand was 1 meter above the ground. The keys fell 10
meters to the floor of the drain.
The following equation describes this situation,
1 - 10 =
-9
What does -9 tell us?

-9 tells us how far it fell to the floor

Step-by-step explanation:

her hand is 1 meter above the ground, the drain is 10 meters deep.

-9 tells us the distance between 1 meter and the bottom of the drain

step-by-step explanation: yes

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
