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: (-4, 4) (-1, 6)

Find the slope m from the two grid points, then solve for b in y = mx + b.

Slope:
m = (6 − 4)/(-1 − (−4)) = 2/3.

Use one point to get b:
b = y − m x = 4 − (2/3)(−4) = 4 + 8/3 = (12+8)/3 = 20/3.

So the y‑intercept is 20/3 (≈ 6.6667). The line is y = (2/3)x + 20/3.
