Question

How do you write an equation of the horizontal line through the point (-1/2,4/5)?

Answer 1

`y=4/5`

Explanation:

A horizontal line has slope 0 (it is parallel to the x-axis), and so we can write an equation in slope-intercept form, where the general formula is:

`y=mx+b; m="slope", b= "y-intercept"`

We can therefore write:

`y=0x+4/5`

The graph looks like this:

graph{0x+4/5 [-6.27, 6.216, -1.697, 4.546]}
