Question

Write an equation in slope-intercept form for the line with y-intercept −5 and slope −2/5

Answer 1

`\large\boxed{y=-(2)/(5)x-5}`

Explanation:

The slope-intercept form of an equation of a line:

`y=mx+b`

m - slope

b - y-intercept

We have

`m=-(2)/(5),\ b=-5`

Substitute:

`y=-(2)/(5)x+(-5)}=-(2)/(5)x-5`
