# How do you find x if a line passes through points (x, 7) and (3, 2) and the slope of the line is 1/2?

Set $\setminus \frac{r i s e}{r u n} = \setminus \frac{7 - 2}{x - 3} = \setminus \frac{5}{x - 3}$ equal to the slope $\frac{1}{2}$. Then "cross multiply" to get $10 = x - 3$. Finally, and 3 to both sides to get $x = 13$.
