Answer:

2y²   +   9

---------------

      15y³

Step-by-step explanation:

Start by identifying the LCD, and then change each fraction so that its denominator is the LCD.

Here the LCD is 15y³, which is evenly divisible by 15y and 5y³.

Focus now on the first fraction:  2 / (15y).  Multiplying numerator and denominator of this fraction by y² results in

y²·2          2y²

--------- → ----------

y²·15y       15y³           ←This is the correct LCD

Multiplying numerator and denominator of the second fraction by 3 results in:

   3·3            9

------------ → ---------

 3·5y³         15y³          ←This is the correct LCD

So now those two original terms look like:

 2y²         9

--------- + --------

 15y³       15y³

and this can be written in simpler form as:

2y²   +   9

---------------

      15y³

Find the slope in (-2,8) and (1,6)
Salsk061 [2.6K]

Formula for slope: \frac{y2 - y1}{x2 - x1}

y₂: 6

y₁: 8

x₂: 1

x₁: -2

Plug them into the slope equation:

\frac{6 - 8}{1 - (-2)}

--> \frac{-2}{1 + 2}

---> -\frac{2}{3}

The slope is -\frac{2}{3}.
