Given :
An equation of line :
2y - mx + b.
To Find :
The y-intercept of the given line.
Solution :
We know, in general equation of line :
y =mx + c
Here, c is the y-intercept.
Now, simplifying given equation till general equation :
[tex]2y =mx + b\\\\y =\dfrac{mx}{2}+\dfrac{b}{2}[/tex]
Therefore, y-intercept is [tex]\dfrac{b}{2}[/tex] .
Hence, this is the required solution.
