Question

Write the equation of a line that is perpendicular to the line y=4 and passes through point (-1, 1)​

Answer 1

Answer:

x = - 1

Step-by-step explanation:

y = 4 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 4

A perpendicular line 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, 1) with an x- coordinate of - 1, thus

The equation of the perpendicular line is x = - 1
