Step 1 :Find the slope of the line using the given point $(3,1)$ and the $x$-intercept $(2,0)$
Step 2 :Use the point-slope form equation $y - y_1 = m(x - x_1)$ where $(x_1, y_1)$ is the given point and $m$ is the slope
Step 3 :Substitute the given point $(3,1)$ and the slope $m=1$ into the point-slope form equation
Step 4 :Simplify the equation if necessary
Step 5 :Write the final answer in point-slope form: \(\boxed{y - 1 = 1(x - 3)}\)
