In the slope-intercept equation of a line, \( y = mx + b \):
-
The variable m represents the slope of the line. This indicates how steep the line is and the direction it goes (positive slope goes up, negative slope goes down).
-
The variable b represents the y-intercept of the line. This is the point at which the line crosses the y-axis, or the value of \( y \) when \( x \) is 0.
So, to summarize:
- m = slope
- b = y-intercept
