Find an equation in point slope form that passes through the points -1,3 and 1,7 show all your work

Step-by-step explanation:

1. Find the slope:

   7 -3/ 1 + 1 = 4/2 = 2 = m

2.  Find b by plugging in the m and one of the points given into y = mx + b

     7 = 2 ( 1 ) + b

     7 = 2 + b

      5 = b

3. Write the equation using the m and the b you just found

 y =2 x + 5

i would need to see the dot plot : )

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
