The mathematic average of a set of numbers

The term 'average' refers to the 'middle' or 'central' point; when used in mathematics the term average refers to a number that is a typical representation of a group of numbers (or data set).

You can calculate it in mean, median or mode.

1st question: y=7x-51

Step-by-step explanation:

So for the first question: *aHem*

You rewrite the equation to be 5=7*8+b. The reason why is because since it will be parellel it will have the same slope, and those coordinates that you gave me I just plugged into equation.

Solve equation: 7*8=56 so now it's 5=56+b. Subtract 56 from both sides. -51=b

Rewrite again into y=7x-51. The reason why is because b means y intercept and you are looking for where to start (y-intercept) and keeping the same slope. Parallel means never touching.
