1. Y – Intercept of a Line
The y – intercept of a line is the point where the line intersects or “cuts through” the y – axis.

2. Y – Intercept of a Line
The y – intercept of a line is the point where the line intersects or “cuts through” the y – axis.
Y intercepts occur where x = 0, so the coordinate point for all y intercepts is ( 0 , y )

3. Y – Intercept of a Line
The y – intercept of a line is the point where the line intersects or “cuts through” the y – axis.
Y intercepts occur where x = 0, so the coordinate point for all y intercepts is ( 0 , y )
In our diagram, you can see the line intersects the y – axis at y = 3

4. Y – Intercept of a Line
The y – intercept of a line is the point where the line intersects or “cuts through” the y – axis.
Y intercepts occur where x = 0, so the coordinate point for all y intercepts is ( 0 , y )
In our diagram, you can see the line intersects the y – axis at y = 3
Y – intercept = ( 0 , 3 )

5. Y – Intercept of a Line
To find the y – intercept of an equation and no graph is available to see where the line crosses the y – axis, substitute x = 0 into the given equation and solve for y .
EXAMPLE : Find the y – intercept of

6. Y – Intercept of a Line
To find the y – intercept of an equation and no graph is available to see where the line crosses the y – axis, substitute x = 0 into the given equation and solve for y .
EXAMPLE : Find the y – intercept of
Let x = 0

7. Y – Intercept of a Line
To find the y – intercept of an equation and no graph is available to see where the line crosses the y – axis, substitute x = 0 into the given equation and solve for y .
EXAMPLE : Find the y – intercept of

8. Y – Intercept of a Line
To find the y – intercept of an equation and no graph is available to see where the line crosses the y – axis, substitute x = 0 into the given equation and solve for y .
EXAMPLE : Find the y – intercept of
So the y – intercept would be ( 0 , 4 )
