Y = 3x + 13
You can get this by using the same slope and then plugging into the equation to find the intercept. <span />
Answer: 
Step-by-step explanation:
1. By definition, an even number is that number that can be divided by two.
2. Therefore, keeping this definition on mind, if you have an even number
, the next consecutive even integer after it can be obtained by adding 2.
3. Then, you can conclude the expression that represents the first consecutive even integer after
is:

To know the initial amount of the radioactive substance, you should read the graph in the y - axis when the x = 0, because at x = 0 this means the intial point of the graph or the initial amount of the substance. so at x = 0 the y = 45 so the initial amount is 45 g
18-6=12 12/2= 6, the answer is 12 or 18.
