Question

Look at this graph:

y
x
-10
-5
5
10
-10
-5
5
10
0


What is the y-intercept?

Answer 1

I can't clearly read the line from the text you pasted. Could you either upload a picture of the graph or tell me two points on the line (or the point where it crosses the y-axis)?

How to find the y‑intercept:
- The y‑intercept is the y‑value where x = 0 (the point where the graph crosses the y‑axis).
- If you know two points (x1,y1) and (x2,y2), compute slope m = (y2−y1)/(x2−x1) and then b = y1 − m·x1; the y‑intercept is b.

If the single number "0" in your text was meant to show the crossing at (0,0), then the y‑intercept is 0. Otherwise please send the graph or two points and I’ll compute it.
