Answer:
Step-by-step explanation:
18x² + 2 = 2 * 9x² + 2 *1
= 2*(9x² + 1)
When the function goes 1 to the right, it goes 2 down. Therefore the direction of the function is

Hence, the function represented is
y = -2x
Answer: b(4) or 4(b)
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
8 units separate -4 and 4
8 divided by 2 (which is the x of slope) is four
Four times 1 (which is y of slope) equals four
3+4 equals seven
(4,7)
The square root of 1296 is 6.
