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, -5) (-1, 2)

Find the slope first:
m = (2 - (-5))/(-1 - (-3)) = 7/2.

Use point-slope (or compute b = y - mx). Using (-1, 2):
b = 2 - (7/2)(-1) = 2 + 7/2 = 4/2 + 7/2 = 11/2.

So the line is y = (7/2)x + 11/2, and the y-intercept is 11/2 (which is 5.5).
