Answer:
A
Step-by-step explanation:
[tex]P_1(2,2) \: \: \: \: \: \: \: P_2(6, 4) \\ \\ y - y_0 = \frac{y_2 - y_1}{x_2 - x_1} (x - x_0) \\ \\ y - 2 = \frac{4 - 2}{6 - 2} (x - 2) \\ \\ y - 2 = \frac{2}{4} (x - 2) \\ \\ y - 2 = \frac{1}{2} (x - 2) \\ \\ y - 2= \frac{1}{2} x - 1 \\ \\ y = \frac{1}{2} x - 1 + 2 \\ \\ y = \frac{1}{2} x + 1[/tex]
