6/9 (2/3) and 2/3. Hope this helps you.
The slope of line D is also -4 because the lines are perpendicular.
That isn’t a question it is a statement
It's C, Y = 2x + 3. This is cause, if we use the table and say that y = 5 and x = 1, then 5 = 1 x 2 + 3 which is correct
F(x) = 2x - 1
subtitute x = 0 to the equation:
f(0) = 2· 0 -1 = 0 - 1 = -1
f(0) = -1
