1) y= 1/2x+2 and I have no idea about 2

Step-by-step explanation:
Let's pick two points on the line:
and
Let's calculate the slope of this line using these points:

With this value of the slope, we can write the general slope-intercept form of the equation as

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

Therefore, the slope-intercept form of the equation is

Answer:
1/36
Step-by-step explanation:
it is the exact same as if both your dice had the numbers {1,2,3,4,5,6}
you said the SUM of the dice that is indicates the answer of the addition of two (or for that matter more) numbers,... the only numbers that would sum 2 is 1+1,... and because you only have two ones (one per die) the answer is the same as if they where die with normal numbers,...
