Interpret the Linear Equation

question 79

Multiple Choice

Interpret the linear equation.
-The speed of a ball dropped from a tower is given by the linear function y = 32x where y is in feet per second and x is the number of seconds since the ball was dropped. Find and interpret the slope and y-intercept of the
Linear equation.

• A) m = 32; The speed of the ball increases 32 feet per second every second. There is no y-intercept to interpret.
• B) m = 32; The speed of the ball is 32 feet per second. b = 0; When the ball is dropped at x = 0, the ball has fallen 0 feet.
• C) m = 32; The speed of the ball increases 32 feet per second every second. b = 0; The speed of the ball was 0 the moment it was dropped.
• D) m = 0; The speed of the ball does not increase as time passes. b = 32; At time x = 0, the ball has fallen 32 feet.

Definitions:

Action Potential

A sudden change in the electrical properties of the neuron's membrane, allowing for the transmission of signals along the neuron.

Ions

Ions are atoms or molecules that have gained or lost one or more electrons, giving them a positive or negative electrical charge.

Membrane

A thin layer of tissue or material that acts as a barrier or separation between different environments or substances.

Resting Potential

The electrical charge across the neuronal membrane when the neuron is not actively firing.
