Asked by Alto saxaphone

how can I find the y intercept if I can't read it directly from the graph because its an improper fraction and/out of view on my limited view of the graph? Two points on exact grid lines: (3, 1) (7, 6)

Find the slope m first:
m = (6 − 1) / (7 − 3) = 5/4.

Use b = y − m x with either point (easier than reading the graph):
b = 1 − (5/4)·3 = 1 − 15/4 = (4/4 − 15/4) = −11/4.

So the y‑intercept is −11/4 (which is −2.75).
