Front

What is point-slope form of a linear equation?

Back

y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

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 the domain of a function?

Back

Front

What does it mean if the domain is all real numbers?

Back

The function can accept any real number as an input.

Front

What is factoring in algebra?

Back

The process of breaking down an expression into simpler components (factors) that, when multiplied together, give the original expression.
