Question

How do you find a standard form equation for the line (0,1) (3,-1)?

Answer 1

`y=-2/3*x+1`

Explanation:

Write a standard equation for a line:
`y=a*x+b`
Put your points in the equation:
`(0,1)`
`1=0*a+b` `=>` `b=1`
`(3,-1)`
`-1=3*a+b=3*a+1`
`-2=3*a` `=> a=-2/3`
Your equation is:
`y=-2/3*x+1`
