Given:
y - 4 = \frac{1}{2}(x - 2)
Step 1: Distribute the slope on the right-hand side.
y - 4 = \frac{1}{2}x - \frac{1}{2} \cdot 2
Step 2: Simplify the right-hand side.
y - 4 = \frac{1}{2}x - 1
Step 3: Add 4 to both sides to solve for y.
y = \frac{1}{2}x - 1 + 4
Step 4: Simplify the equation.
y = \frac{1}{2}x + 3
Thus, the slope-intercept form is y = \frac{1}{2}x + 3 .
