Answer:
1. y=3x-2
2. y=-1/4x+5
These equations are in slope-intercept form (y=mx+b). IN this equation m represents the slope and b represents the y intercept. Therefore, y=3x-2 and y=-1/4x+5 are correct

Answer:
![S_6 = -63](https://tex.z-dn.net/?f=%20S_6%20%3D%20-63%20)
Step-by-step explanation:
The sequence above is a geometric sequence.
The common ratio (r) = ![\frac{-6}{3} = \frac{12}{-6} = -2](https://tex.z-dn.net/?f=%20%5Cfrac%7B-6%7D%7B3%7D%20%3D%20%5Cfrac%7B12%7D%7B-6%7D%20%3D%20-2%20)
The common ratio < 1, therefore, the formula for the sum of nth terms of the sequence would be: ![S_n = \frac{a_1(1 - r^n)}{1 - r}](https://tex.z-dn.net/?f=%20S_n%20%3D%20%5Cfrac%7Ba_1%281%20-%20r%5En%29%7D%7B1%20-%20r%7D%20)
a1 = 3
r = -2
n = 6
Plug in the values into the formula
![S_6 = \frac{3(1 - (-2^6)}{1 - (-2)}](https://tex.z-dn.net/?f=%20S_6%20%3D%20%5Cfrac%7B3%281%20-%20%28-2%5E6%29%7D%7B1%20-%20%28-2%29%7D%20)
![S_6 = \frac{3(1 - (64)}{1 + 2}](https://tex.z-dn.net/?f=%20S_6%20%3D%20%5Cfrac%7B3%281%20-%20%2864%29%7D%7B1%20%2B%202%7D%20)
![S_6 = \frac{3(-63)}{3}](https://tex.z-dn.net/?f=%20S_6%20%3D%20%5Cfrac%7B3%28-63%29%7D%7B3%7D%20)
![S_6 = -63](https://tex.z-dn.net/?f=%20S_6%20%3D%20-63%20)
area of triangle formula = ½ × B × H
28in2 = ½ × B × (8)
28in2 = 4 × B
28 ÷ 4 = B
Therefore, length of base = 7 inches
i hope my solution helps :))
