Question

When given a graph, how can you determine the y-intercept in a linear function?

Please help if you can :)

Answer 1

Answer: By looking at where the line passes on the y-axis.

Explanation:

If the line passes on -2 on the y axis, then the y intercept is -2. Now in a linear equation, the intercept would be b in the equation mx+b. So if the equation was 2x +9, then the y intercept would be 9.

Hope this helps!!

Answer 2

It's called the "y-intercept", and it's the value of the point where the line intersects the y-axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y-axis. This point will always have an x coordinate of zero.
