Answer
The slope of the given equation is 0 and the y-intercept is 3. The graph of this function is a horizontal line passing through the point (0, 3).
1Step 1: Rewrite the Equation in Slope-Intercept Form
Start by rearranging the given equation to get it in the form \(y = mx + b\). The given equation is \(3y - 9 = 0\). If we divide everything by 3, we find that \(y - 3 = 0\) or \(y = 3\).
2Step 2: Identify the Slope and Y-Intercept
Now that we have the equation in slope-intercept form, we can identify the slope (m) and y-intercept (b). In this equation, it can be noticed that there is no x term, so the slope (m) equals to 0. This means that the line is horizontal. The y-intercept (b) is the constant term, which is 3 in this equation. So, for the given equation, the slope is 0 and the y-intercept is 3.
3Step 3: Graph the Linear Function
For graphing the function, draw a horizontal line that passes through the y-axis at the point y = 3. A point on this line can be represented as (x, 3) for any value of x since y is always equal to 3.
