Question

How do you write an equation of a line given m=0 and b=2?

Answer 1

`y=2`

Explanation:

The slope-intercept equation is given by `y=mx+b`

Knowing that `m=0` and `b=2` the equation now looks like `y=0x+2` or `y=2`

`y=2` is a horizontal line that crosses the y-axis at `(0,2)`

Here's a graphical look,
