Answer 1

16)
`y=(1)/(4)x +5`

17) y = -x - 4

18) y = -2x - 1

19) y = -2x

20)
`y=(-5)/(3) -3`

Explanation:

With the two points you find the slope using
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
