Answer:

See explanation.

Step-by-step explanation:

We need a point and a slope to have a point slope equation.

[tex]y-y_{1}=m(x-x_{1})[/tex]

We need a slope and y-intercept to write in slope intercept form.

[tex]y=mx+b[/tex]

A) [tex]y-1=\frac{1}{2}(x+4)[/tex] or [tex]y=\frac{1}{2}x+3[/tex]

B) [tex]y+1=-1(x-2)[/tex]

C) [tex]y-1=0(x-1)[/tex]

D) [tex]y=-3x+8[/tex]
