1. $y=7x-1$

2. $y=3x+b$
 Sub (1, -5) into equation to find 'b'
$-5=3(1)+b$
$-8=b$

$y=3x-8$

3. $x=-7$

4. $y=4$

Answer:

n > -2 or n < -3

Step-by-step explanation:

|2n+5| > 1

We have two solutions one positive and one negative. Remember to flip the inequality symbol for the negative

2n+5 > 1 or 2n+5 < -1

Subtract 5 from each side

2n+5-5 > 1-5 2n+5 -5 < -1 -5

2n >-4 2n < -6

Divide by 2

2n/2 > -4/2 2n/2 < -6/2

n > -2 or n < -3
