Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, y).

Front

Given f(x) = -4x - 10 and f(x) = 10. Find x.

Back

x = -5

Front

What is the x-intercept of a function?

Back

The x-intercept is the point where a line crosses the x-axis. It is represented as (x, 0).

Front

What are the x-intercept and the y-intercept of the function f(x) = -4x + 2?

Back

x-intercept of (1/2, 0) and y-intercept of (0, 2).

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

What is the solution of the system of equations: x + 2y = 23 and 4x - y = -7?

Back

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

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