How do you calculate the slope of a line passing through two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the factored form of the expression m^2 - 13m - 30?

Back

(m - 15)(m + 2).

Front

What is the definition of the domain of a function?

Back

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

Front

What is the definition of the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

What does the inequality y ≤ -4x represent graphically?

Back

It represents the area below the line y = -4x, including the line itself.

Front

How do you find the y-intercept of a linear equation in the form y = mx + b?

Back

The y-intercept is the value of y when x = 0, which is b.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.
