Back

Point-slope form.

Front

Write the equation of a line PERPENDICULAR to y = -2x + 1 that passes through the point (2, 3).

Back

Front

What is the solution to the system of linear equations? (2x + 3y = 12, x - y = 1)

Back

(3, 3).

Front

What is the solution to this system? y = 4x + 3, 2x - 3y = 21

Back

(-3, -9).

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

Define the term 'slope' in the context of a linear equation.

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

What is the standard form of a linear equation?

Back

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