Answer:
3
Step-by-step explanation:
Remember the order of operations using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). So, you get 18 - 6 / 5-1 = 12/4 = 3
The slope is : -5/2
The equation is : y=-5/2x + 5
When solving for you it would equal 6 so U=6 hope that helps
0.2 if you mean 2/10 or 2.5 if you mean 10/2
