D because the question would have to be multiply the numbers in a way that would get you the cost of 2 rubber stamps
Y = -2x + 4
Therefore, gradient = -2
(-3,9)
y = m(x - x1) + y1
y = -2(x - (-3)) + 9
y = -2(x + 3) + 9
y = -2x - 6 + 9
y + 2x = 3
A = 3. Hope this helps! (Was trying to show the work but I can't take pictures at the moment.)
The principal, real, root of:

Complementary angles are angles that add up to 90º. For example, 30º and 60º.
Supplementary angles are angles that add up to 180º. For example, 120º and 60º.
