What Is a Linear Relationship?
A linear relationship is a term used to describe a straight-line relationship between a variable and a constant.
Define a Table Of Values
A table of values is a list of numbers that are used to substitute one variable, such as within an equation of a line and other functions, to find the value of the other variable, or missing number.
Four More Than The Number is 45
X + 4 = 45
X - 16 = 85
X = 101
X/6 - 14 = 16
X = 5
What Is The Difference Between a Variable and a Constant?
A constant does not change its value over time. A variable on the other hand changes its value dependent on the equation.
What Is This? -> 3x + 2

Jason bought a soft drink for 2 dollars and 9 candy bars. He spent a total of 38 dollars. How much did each candy bar cost?
9X + 2 = 38
9X = 38 - 2
9X = 36
X = 36/4
X = 9 Dollars

X = 20
On Monday, 264 students went on a trip to the zoo. All 5 buses were filled and 9 students had to travel in cars. How many students were in each bus ?
5X + 9 = 264
5X = 264 - 9
5X = 255
X = 255/5
X = 52 students
