Is 9 a solution to the equation 21=3p-5? Show work

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

21 = 3p - 5

<u>Step 1</u> : Add 5 on both sides

21 + 5 = 3p

26 = 3p

3p = 26

<u>Step 2</u> : Divide 3 on both sides

p = 26/3

Hence, the solution of the given equation is 26/3, not 9.

You need to use the slop formula (y2-y1/x2-x1)

9 -3/5--3
6/5+3
6/8
3/4
The slope is 3/4
