Front

How do you determine if a point is a solution to a system of equations?

Back

Substitute the point's coordinates into both equations; if both equations are true, the point is a solution.

Front

What is the y-intercept in the equation y = 2x - 7?

Back

The y-intercept is -7, which is the value of y when x = 0.

What is the general form of a linear equation?

Back

The general form is Ax + By = C, where A, B, and C are constants.

Front

How can you graph a linear equation?

Back

You can graph a linear equation by plotting the y-intercept and using the slope to find another point.
