![\huge\boxed{\sf{b=55\:(b=y-intercept\:;)}}](https://img.qammunity.org/2023/formulas/mathematics/college/gyng98t94hsrwnka5qxuf3ymljzg6i6l4r.png)
Explanation:
Hello.
The y-intercept of a line is a point where the graph touches the y-axis.
Y-intercepts always have an x-coordinate of 0.
Now, what is the y-intercept?
If we have a point (0, b) then b is the y-intercept.
This is just a formula, so don't think that the y-intercept is b, okay?
The y-intercept is b, but only in formulae. :)
Using the formula, we can deduce that
the y-intercept is 55.
I hope it helps.
Have a great day.
