Question

write an equation in slope-intercept form for a line that has a slop of -1 and intersects the y-axis at (0,3)

Answer 1

`y=-x+3`

Explanation:

we know that

The equation of a line in slope -intercept form is equal to

`y=mx+b`

where

m is the slope

b is the y-intercept

In this problem we have

`m=-1\\b=3`

substitute

`y=-x+3`
