Front

What is the standard form of a linear equation?

Back

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

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

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

What is the x-intercept in the equation y = 3x - 6?

Back

2 (set y = 0 and solve for x).

Front

How do you graph the equation y = 2x + 1?

Back

Start at (0,1) and use the slope of 2 to find another point.
