## Week #8 -Math 10

This week in math 10 we learned about graphing! First things first it’s important to understand what a variable is and that there are two types of variables, **discrete **and **continuous**. Variables are basically when the data or clues are given to us and it’s our job to find out where they go on a graph to showcase it a different way.

A discrete variable basically means a whole number / a number that you cannot divide. In other words, they don’t have an infinite number of values.A good example to remember this is how many people are in your household? As you cannot divide people in half (I would not like to see it anyway!), it counts as a discrete variable! Or maybe, how many cars sold from a dealership per month. As you cannot sell a fraction of a car, it counts as a discrete variable! When you’re graphing the dots and using a discrete variable, the dots on the graphs are **not **connected because the space between dots does not have value and there is nothing that is in between the dots on the graph as it cannot be divided.

A continuous variable meansthat there’s, in theory, an infinite number of possibilities. This variable is used to measure things like time, distance, weight, etc.The reason that they qualify as continuous is becausethey are not whole numbers. When you’re graphing the dots and using a continuous variable, the dots on the graphs are connected because the space between dots also has value.
