First find the slope and then use it to determine if the line is rising, falling, horizontal, or vertical:
1. 5-y=7+ 2/3x
m= means this line is
2. 2x+3y=4x+2y
m= means this line is
3. 3y+6=12x
m= means this line is
4. 4(2-y)=12
m= means this line is
5. 2y= 2/3 x - 14
m= means this line is
6. 6(x+2y) =9y
m= means this line is
7. 3x+6=12
m= means this line is

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
