1. **State the problem:** We need to find the solution to the system of linear equations:
$$-\frac{1}{2} y = \frac{1}{2} x + 5$$
and
$$y = 2x + 2$$
This means finding the point $(x,y)$ where both lines intersect.
2. **Rewrite the first equation to express $y$ in terms of $x$: **
Multiply both sides by $-2$ to isolate $y$:
$$-2 \times \left(-\frac{1}{2} y\right) = -2 \times \left(\frac{1}{2} x + 5\right)$$
$$\cancel{-2} \times \cancel{-\frac{1}{2}} y = \cancel{-2} \times \left(\frac{1}{2} x + 5\right)$$
Simplifying the left side:
$$y = -2 \times \frac{1}{2} x - 2 \times 5$$
$$y = -x - 10$$
3. **Set the two expressions for $y$ equal to find $x$: **
Since $y = -x - 10$ and $y = 2x + 2$, set them equal:
$$-x - 10 = 2x + 2$$
4. **Solve for $x$: **
Add $x$ to both sides:
$$-x - 10 + x = 2x + 2 + x$$
$$-10 = 3x + 2$$
Subtract 2 from both sides:
$$-10 - 2 = 3x + 2 - 2$$
$$-12 = 3x$$
Divide both sides by 3:
$$\frac{-12}{\cancel{3}} = \frac{3x}{\cancel{3}}$$
$$-4 = x$$
5. **Find $y$ by substituting $x = -4$ into one of the equations: **
Using $y = 2x + 2$:
$$y = 2(-4) + 2 = -8 + 2 = -6$$
6. **Final answer:** The solution to the system is
$$(x,y) = (-4, -6)$$
This means the two lines intersect at the point $(-4, -6)$ on the coordinate plane.
