Answer:
1.

2.

Explanation:
1. To find the slope we will use the slope formula
.
We have two points located at (0,0) and (1,2)
Use these points and plug it into the slope formula.



Our slope in this case is 2. So,
.
2. To write the equation, we must use

We found out that m=2. So we will use that in our equation.
b is usually the y-intercept, but since our y-intercept is 0, we do not need to write it.
So, your answer is
