Answer:
[tex]b=5[/tex]
Step-by-step explanation:
The given equation is:
[tex]y=3x+5[/tex]
To find the point where this line intersect the y-axis, we put x=0 into the given equation.
When x=0, we have [tex]y=3(0)+5[/tex].
This implies that; y=5.
The y-intercept is (0,5).
Comparing (0,5) to (0,b), we can conclude that; b=5
