The expressions that have a sum of 6 are Options C and D
<h3>How to determine the sum</h3>
In this case, we use the following rules
(-) + (-) = -
(+) + (+) = +
(+) + (-) = -
(-) + (+) = -
From the first case
8 + 2 = 10
(-4) + (-2) = -4 + -2 = -6
(-3) + 9 = -3 + 9 = 6
7 + (-1) = 7 - 1 = 6
Thus, the expressions that have a sum of 6 are Options C and D

The slope of the line we seek must me the same as the slope of the given line because THE LINES ARE PARALLEL.
The two lines never meet.
The slope of the given line is -7.
See it?
Plug -7 and the given point into the point-slope formula.
y - (-6) = -7(x - 9)
Solve for y.
y + 6 = -7x + 63
y = -7x + 63 - 6
y = -7x + 57
