Find the point-slope form of the line with the given slope which passes through the Slope $=-\frac{1}{2} ;$ Line passes through the point $(4,9)$ Write an equation for the line in point-slope form. (Use integers or simplified fractions for any numbers in the equation.)

Step 1 ：Given the slope \(m = -\frac{1}{2}\) and the point \((4,9)\) through which the line passes.

Step 2 ：Substitute the given values into the point-slope form equation \(y - y_1 = m(x - x_1)\).

Step 3 ：Substituting \(m = -\frac{1}{2}\), \(x_1 = 4\), and \(y_1 = 9\) into the point-slope form equation, we get:

Step 4 ：\(y - 9 = -\frac{1}{2}(x - 4)\)

Step 5 ：So, the point-slope form of the line is \(\boxed{y - 9 = -\frac{1}{2}(x - 4)}\).
