Question

Choose the correct answer. Choose the equation of a line that is perpendicular to the x-axis and passes through the point (1, -2).
a. x= -2

b. x= 1

c. y= -2x + 1

d. y= -2​

Answer 1

Answer:

b

Step-by-step explanation:

A line perpendicular to the x- axis is a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (1, - 2 ) with x- coordinate 1 , then

x = 1 ← equation of perpendicular line
