Given a slope of 2/3 and a y-intercept of -3, what is the equation of the line?

Back

y = 2/3x - 3

Front

In slope-intercept form (y = mx + b), what does 'm' represent?

Back

The slope (rate of change)

Front

What is the general form of a linear equation?

Back

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

Front

What does the y-intercept represent in a linear equation?

Back

The point where the line crosses the y-axis.

Front

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

Back

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