Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What equation would have an undefined slope?

Back

x = 5

Front

Write an equation that represents a culture of bacteria that begins with 5000 cells and dies by 30% each year.

Back

y=5000(0.7)^x

Front

What does the term 'slope' refer to in a linear equation?

Back

The slope is the measure of the steepness of a line, represented as 'm' in the equation y = mx + b.

Front

What is the y-intercept of the function f(x) = 3x + 4?

Back

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is an exponential decay function?

Back

A function that decreases at a rate proportional to its current value, often represented as y = a(1 - r)^t.

Front

What does 'domain' refer to in a function?

Back

The set of all possible input values (x-values) for the function.
