Question

Select the equation of the line that passes through the point (3, 5) and is perpendicular to the line x = 4

y = 5

x = 5

y = 4

x = 3

Answer 1

if line is perpendicular to x=4 then it would be a horizontal line
so it can be either y=5 or y=4

Answer 2

try to trace the line on the graph
