The y-intercept on a first quadrant graph is where the line starts.

​​Y-Intercept on 1st quadrant graph.

You can write your answer as a coordinate point: (0,4)
OR y-int: 4

​​How do you write the answer?

No, the answer is written the same for this graph:
coordinate point: (0, 1.8)
OR y-int: 1.8

Will the answer look different depending on the graph?
