Question 988922
#1,2,3, just use the formula for slope.  Vertical change divided by horizontal change.


#4, simply plug into point-slope equation form.
{{{y-(-1)=(-1/5)(x-(-3))}}} and simplify this.
{{{y+1=-(1/5)(x+3)}}}

{{{y=-(1/5)x-3/5-5/5}}}
{{{y=-(1/5)x-8/5}}}
Refer to the given point and slope to help in graphing.

The format for point-slope form is for a line containing point (u,v) and having slope m, the equation can be shown as y-v=m(x-u).
