We are given a linear function $f(x) = \frac{2}{3}x - 4$. We need to identify the slope, the vertical intercept (y-intercept), and the horizontal intercept (x-intercept). Finally, we need to draw the graph of the function.

1. Problem Description

We are given a linear function f(x)=23x4f(x) = \frac{2}{3}x - 4. We need to identify the slope, the vertical intercept (y-intercept), and the horizontal intercept (x-intercept). Finally, we need to draw the graph of the function.

2. Solution Steps

The given linear function is in the slope-intercept form, y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.
In our case, f(x)=23x4f(x) = \frac{2}{3}x - 4, so the slope m=23m = \frac{2}{3} and the y-intercept b=4b = -4. The y-intercept is the point (0,4)(0, -4).
To find the x-intercept, we set f(x)=0f(x) = 0 and solve for xx:
0=23x40 = \frac{2}{3}x - 4
23x=4\frac{2}{3}x = 4
x=432x = 4 \cdot \frac{3}{2}
x=6x = 6
So, the x-intercept is (6,0)(6, 0).
The slope is 23\frac{2}{3}. The y-intercept is -4, and the x-intercept is
6.

3. Final Answer

Slope: 23\frac{2}{3}
Vertical Intercept: -4
Horizontal Intercept: 6
