Graph the linear equation. \[ f(x)=-2 x+5 \]

Step 1 ：To graph the linear equation \(f(x)=-2x+5\), we need to plot it on a 2D graph.

Step 2 ：We generate a range of x values and then calculate the corresponding y values using the equation.

Step 3 ：Then we plot these points on the graph.

Step 4 ：\(\boxed{\text{The graph of the linear equation } f(x)=-2x+5 \text{ is a straight line with a negative slope of -2 and y-intercept of 5. The line decreases as x increases.}}\)
