Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2. (1 point)?
please show work~!

x = -2 is a vertical line
We need a horizontal line with y = 1
y = 1

Notice that x = -2 is a vertical line since any coordinate on x = -2 must take the form:
(-2, c), for some c.
It should be apparent that all such points form a vertical line.
Any line perpendicular to a vertical line must be horizontal; thus, the required line is the horizontal line that passes through (2, 1), which is y = 1.
I hope this helps!

x=-2 is a vertical line, so the line perpendicular to x=-2 will be horizontal and ergo have a slope (m) of 0.
1=0(2) + b
So the line will be y=1
