1. **State the problem:** We are given two linear equations:
$$y = \frac{2}{3}x + 2$$
and
$$y = 2x - 6$$
We want to analyze these lines, find their intersection point, and understand their slopes and intercepts.
2. **Recall the formula and rules:**
- The slope-intercept form of a line is $$y = mx + b$$ where $$m$$ is the slope and $$b$$ is the y-intercept.
- The intersection point of two lines is where their $$y$$ values are equal.
3. **Set the two equations equal to find the intersection:**
$$\frac{2}{3}x + 2 = 2x - 6$$
4. **Solve for $$x$$:**
Subtract $$\frac{2}{3}x$$ from both sides:
$$2 = 2x - 6 - \frac{2}{3}x$$
Rewrite the right side:
$$2 = \left(2 - \frac{2}{3}\right)x - 6$$
Calculate the coefficient:
$$2 - \frac{2}{3} = \frac{6}{3} - \frac{2}{3} = \frac{4}{3}$$
So:
$$2 = \frac{4}{3}x - 6$$
Add 6 to both sides:
$$2 + 6 = \frac{4}{3}x$$
$$8 = \frac{4}{3}x$$
5. **Isolate $$x$$:**
$$x = \frac{8}{\frac{4}{3}} = 8 \times \frac{3}{4}$$
Show cancellation:
$$x = \frac{\cancel{8}}{\cancel{4}} \times \frac{3}{1} = 2 \times 3 = 6$$
6. **Find $$y$$ by substituting $$x=6$$ into one of the equations:**
Using $$y = 2x - 6$$:
$$y = 2(6) - 6 = 12 - 6 = 6$$
7. **Interpretation:**
- The lines intersect at the point $$(6, 6)$$.
- The first line has slope $$\frac{2}{3}$$ and y-intercept 2.
- The second line has slope 2 and y-intercept -6.
- Since the slopes are different, the lines are not parallel and intersect at exactly one point.
**Final answer:** The two lines intersect at the point $$(6, 6)$$.
