What is the y-intercept of this graph?

Answer:
The y-intercept of the graph is at (0, 1)
Looking at the graph where x=0, we can see it is touching the second dash from the origin (0,0) going vertically.
The increments of the dashes are 0.5, so the second dash occurs at y=1.
Therefore the y-intercept occurs at (0,1)
