"Please Excuse My Dear Aunt Sally<span>". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".
</span><span> we follow PEDMAS simply because that's the accepted convention, but we have the convention because it fits common cases well and makes mathematical expressions easier to read.

What is PEMDAS you ask right?well PEMDAS is a thing you use to solve equations with either parentesis,exponets,when adding,subtracting,multiplying,and dividing.for example, (4+9)20÷5.the first thing that you'll do is what is in the parentesis.4+9=13.then,20÷5=4.finally since there isnt a sign on what to do with 13 &4 you just multiply.4×13=52.we use PEMDAS so it can add order when solving a problem like the example.

The points (2,-5) and (5,r) lie on a line with slope 2. Find the missing coordinate r.
Andrew [12]

Answer: r = 1

Step-by-step explanation:

The slope of a line can be represented as \frac{y_2-y_1}{x_2-x_1}.  Plugging in the following values would provide you with:

\frac{(r)-(-5)}{(5)-(2)} =2

\frac{r + 5}{3}  = 2

r + 5 = 6

r = 1

Hope it helps :) and let me know if you want me to elaborate on anything.
