Answer:

y = 2x + 5

Step-by-step explanation:

Slope = (-1-7)/(-3-1) = -8/-4 = 2

Using y - y1 = m(x - x1)

y - 7 = 2(x - 1)

y = 2x - 2 + 7

y = 2x + 5

Use long division.

                                     y - 1
         -------------------------------
y³+1  | y⁴  - y³  + 2y²  + y  - 1
          y⁴                    + y
         -------------------------------
               - y³  + 2y²         - 1
               - y³                    - 1
              ---------------------------
                         2y²

Answer:  y - 1 + 2y2 ÷ y³+1

Note:  
The correct answer should be written with parenthesis, as y - 1 + y²/(y³+1) in order to avoid ambiguity.

18

Step-by-step explanation:

Intersecting Secants Theorem:

6(x + 6) = 8(8 + 10)
