The slope of a line that passes through the points (x1, y1) and (x2, y2) is computed as follows:
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
then, the slope that passes through K(2,2) and S(5,4) is:
![m=(4-2)/(5-2)=(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/exvff5ymga2x1xrex3cikgvscuseb0fsy4.png)
Two lines are parallel if they have the same slope, then the slope of a line parallel to KS is 2/3
