A bucket is used to fill a large cylindrical vat with water. After pouring buckets of water into the vat, the height of water in the vat was 3 feet. After pouring 16 buckets of water, the height was 6 feet. Let y represent the height of water in the vat (in feet) and x represent the number of buckets poured into the vat. Write a linear equation to estimate the height of the water based on the number of buckets poured in. Express numbers as decimals or integers. The linear equation in slope-intercept form is ____
