First we have the following equation:
a - b = 0
We clear one of the variables depending on the other:
a = b
Therefore we have to for the following expression:
a + b
We can substitute one of the variables, obtaining:
a + a = 2a
Equivalently:
b + b = 2b
Answer:
a + b = 2a
or
a + b = 2b
There are six numbers that can come up when the dice is rolled
the sample space is{ 1 2 3 4 5 6}
hence p(no. <= 6) = 6/6 =1
Step-by-step explanation:

Y=-1x+6
You need to use the slope formula to find the slope of the points, and then find the y-intercept.
