## anonymous 4 years ago can someone help me go through step by step with this one so i can do the rest of the problems by myself......... 2.Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2. (1 point)

1. anonymous

first you need to know that $x=-2$ is vertical, and therefore a perpendicular line will be horizontal

2. anonymous

then you need the fact that a horizontal line has the equation $y=\text{number}$

3. anonymous

so if it passes through (2,1) since the y value is 1, it must be the line $y=1$
