Each number goes up by multiplying by 2.
For example, the 1 got to 2 by 1 x 2 and 2 got to 4 by 2 x 2 = 4.
You would continue this pattern by doing 8 x 2 = 16 for the first blank.
16 x 2 = 32 for the second blank
32 x 2 = 64 for the third blank
64 x 2 = 128 to check your work.
So the answer would be: 1, 2, 4, 8, 16, 32, 64, 128
The answer is A. Just remember the acronym for foil.

I think c is right answer
Answer:
B, ![-\frac{1}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
This problem is essentially asking one to envision a line passing through the set of points on the coordinate plane, then to find the constant of proportionality of that line. The constant of proportionally, also known as the rate of change, or the slope, is a number that can be used to describe the range that happens between points on a line. The following formula can be used to find the slope of a line passing through a set of points.
![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Where the points (
) and (
) are points on the line.
As one can see, on the given coordinate plane, the points (
), and (
) are on the coordinate plane. Substitute these points into the formula to find the slope of the line, then simplify to evaluate the equation and find the slope,
![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)

![=\frac{-2-(-1)}{(4)-(2)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-2-%28-1%29%7D%7B%284%29-%282%29%7D)
![=\frac{-2+1}{4-2}\\\\=\frac{-1}{2}\\\\=-\frac{1}{2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-2%2B1%7D%7B4-2%7D%5C%5C%5C%5C%3D%5Cfrac%7B-1%7D%7B2%7D%5C%5C%5C%5C%3D-%5Cfrac%7B1%7D%7B2%7D)
2 ( x - 4 ) < 5x
