The equation $y = 9x - 1$ is in slope-intercept form, where:

• m = 9 is the slope of the line, and
• b = -1 is the y-intercept, which means the line crosses the y-axis at $y = -1$.

Characteristics of this linear equation:

1. The slope of 9 means that for every 1 unit you move to the right along the x-axis, the y-coordinate increases by 9 units.
2. The y-intercept $b = -1$ means that the line crosses the y-axis at the point (0, -1).

If you need to find specific points on this line or need help graphing it, feel free to ask!

Tip:

To quickly graph a linear equation, start by plotting the y-intercept, and then use the slope to determine other points. For example, from $(0, -1)$, you can move 9 units up and 1 unit to the right to plot the next point!
