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, 6) (1, 3)

Use the two known points to get the line equation, then evaluate at x = 0.
1. Slope m = (6 − 3) / (3 − 1) = 3/2.
2. Use y = mx + b with point (1, 3): 3 = (3/2)(1) + b → b = 3 − 3/2 = 3/2.
So the y-intercept is 3/2 (which is 1.5), i.e. the point (0, 3/2).
