Answer:
Option B.
Step-by-step explanation:
It is given that △ABC is reflected to form △A'B'C' .
It is given that the vertices of triangle ABC are A(4,1), B(6,3) and C(2,4).
From the given figure it is clear that vertices of triangle A'B'C' are A'(-4,1), B'(-6,3) and C(-2,4).
The relation between preimage and image is defined by the rule
Reflection across y-axis represented by the above rule.
It means the △ABC is reflected across the y-axis to form △A'B'C' .
Therefore, the correct option is B.

Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 3 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, hence
y = - x + c ← is the partial equation of the perpendicular line
To find c substitute (3, 1) into the partial equation
1 = - 1 + c ⇒ c = 1 + 1 = 2
y = - x + 2 ← equation of perpendicular line
