Yessss that should be correct
Answer:
The line given is equal to y=-x+7 (Through rearranging)
To find the new line, we substitute the given coordinates (5,8) in the equation without the given y-intersect (+7):
-8=-5+c
c=-3
The line parallel to x+y=7 that passes through the point (5,-8) is y=-x-3
X + (-y) = -2.3 + ( - (-5.9) ) = -2.3 + 5.9 = 3.6
15% of 80 is 12.
To check this, you can multiply 80 x 0.15, which gives you an answer of 12.
