Question

Find an equation of the line passing through the given points. Use function notation to write the equation.(-3,-4) and (-6,-3)

Answer 1

The slope of the line is

`m=(-3--4)/(-6--3)=(1)/(-3)`

And now we find the y-intercept and to do that we use the point (-3, -4):

`-4=-(1)/(3)(-3)+b`
`-4=1+b`
`b=-5`

Hence, the equation of the line is

`y=-(1)/(3)x-5`
