ANSWER

EXPLANATION
The required equation passes through:
(4,3) and is perpendicular to x+y=4.
Rewrite the given equation in slope-intercept form:

The slope of this line is -1.
The slope of the required line is perpendicular to this line, so we find the negative reciprocal of this slope.

The equation of the line can be found using:

We substitute the slope and point to obtain:

We simplify to get:


The required equation is
162 / 2 = 81
the answer is D
