The function modeled by the pattern is y = 3x, since the slope is 3, and the y-intercept is 0.
Therefore, for any image number x, the number of blocks y can be calculated by y = 3x.
image 1 = three blocks
image 2 = six blocks
image 3 = nine blocks
image 4 = twelve blocks
Analyze the tile pattern and write a function for the pattern. Use x for the image number and y for the number of tiles in each image.
The function modeled by the pattern is __, since the slope is __, and the y-intercept is __.
