Answer:
B. y = -x + 8
Step-by-step explanation:
The line is perpendicular to line whose equation is:
y = 2x + 4 and;
passes through point (4,6) .
The product slopes of two perpendicular lines is -1.
The slope of the line whose equation is y = 2x + 4 is; 2
Let the slope of the perpendicular line (l2) be
=
Taking another point xy on line l2;
Cross multiplying this gives;
y = -x + 8 which is the equation of the perpendicular line!
