The numbers 1-6 were put into a coffee mug and pick out one at a time and then replaced after being picked. The table below shows how many times each number was picked.

How many times was

1. 3x – 6y = 12 2. x + 5y = -25

To find the y-intercept, you plug in ZERO FOR X

3(0) – 6y = 12

-6y = 12

-6 -6

y = -2

(0,-2)

(0) + 5y = -25

5y = -25
