This is how many solutions a linear equation will have.
What is one?
This is the algebraic process of getting a single variable alone on one side of the equal sign.
What is isolation?

What are less than, greater than, less than or equal to and greater than or equal to?
This is slope-intercept form.
What is y=mx+b?
These type of numbers can be found on a number line.

Saving ten dollars a month for a period of time can be modeled using a linear function. This is what we refer to the ten as within the function.
What is the rate of change/slope/coefficient of x?
This is the value of y in: 3x + y = 19
What is 19 - 3x or -3x + 19?
*Bonus* For an additional 200, what property or equality allows us to write what y equals in both ways?
What is infinite?
This is the value of x at the y-intercept
What is zero - (0, b)?
These numbers can be written as a fraction.
What are rational numbers?
A cell phone plan charges a base fee per month of $15. This is what we refer to this unchanged value in a linear function.
What is the constant/b-value/starting value/initial value/y-intercept?
This is the step needed to isolate x: (9/5)x = y + 5
What is multiply both sides by the reciprocal of the coefficient (5/9)?
A closed circle on a number line is indicated using this symbol in interval notation.
What is a [bracket]?
This is the calculated rate of change between these two points on a given line: (15, 10) and (18, 20).
What is 10/3?
A number under the square root is considered irrational when it is not one of these.
What is a perfect square?
