What does the equation of a line in slope-intercept form represent?

Back

The equation of a line in slope-intercept form, y = mx + b, represents a linear relationship where m is the slope and b is the y-intercept.

Front

What is the slope of the line represented by the equation y = -4x + 95?

Back

The slope of the line is -4, indicating that for each additional absence, the score decreases by 4 points.
