Respuesta :

easy

the line we have is y=2.5
a perpendicular line to y=c where c is a constant is x=c where c is also a constant

just find what that constant is

point (3,-1)
x=3 and y=-1
so the equation is x=3 so that it will pass through that point


answer is x=3

we know that

The equation of the given line in the graph is

[tex]y=2.5[/tex]

The given line is parallel to the x-axis

so

the perpendicular line to the given line will be parallel to the y-axis and the equation will be equal to the x-coordinate of the given point [tex](3,-1)[/tex]

The x-coordinate of the point is

[tex]x=3[/tex]

therefore

the answer is the option

[tex]x=3[/tex]
