1. Answer:

   -3

   Step-by-step explanation:

   Point slope means y-y=m(x-x)

   m is the slope

   in this case, -3 is the slope

   y+2=-3(x+1)

   2. Use the coordinates of the labeled points to find a point slope equation of this line -5,2 -1,0.

   The answer would be (slope-intercept): y=-0.5x-0.5

   To find the answer, you’d find the slope from the two points…

   y=-0.5x+b

   then substitute y and x and add in x and y values from a point (I’ll use the point -5,2)

   2=-0.5(-5) + b

   simplify and isolate to get

   b=-0.5
