Unit 2 Review Part 2

Front

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

Back

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

Front

Identify the slope and a point from the equation y - 1 = 3(x + 2).

Back

Slope (m) = 3; Point = (-2, 1)

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

Convert the equation -y = x + 3 to standard form.

Back

x + y = -3.

Front
