D) because “y is” means “y equals” leaving only 2 choices, and it said “6 less than the independent variable, 6. (Y=6-x)
The answer to the question is b
F(x)=x^2-4x+7
My work is attached below
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
Y is 9 because 2 times 5 is 10, then you take that same 10 and subtract 1 and then you have 9
