Question

What is the equation of the line whose y-intercept is 3 and slope is 1? y = x - 3 y = x 3 y = 3x 1

Answer 1

The equation is y=1x+3. The line equation is y=mx+b. m being the slope and the b being the y-intercept.

Answer 2

The answer is y=x+3

Explanation:

An equation for a line which is not vertical can be written in the form

`y=mx+b`

where
`m` is its slope and
`b` is its y-intercept.

So, if you replace
`m` and
`b` in the last equation by 1 and 3 respectively, you have the equation of the line:

`y=1x +3`

but, this is the same as

`y=x+3`
