Real # Systems
These numbers cannot be expressed as fractions and include numbers like π, e, and √...
What are irrational numbers?
The formula y=mx+b represents this type of equation.
What is the slope-intercept form of a linear equation?
The formula to find the slope between two points (x1,y1) and (x2,y2) is given by this expression.
What is y2-y1/x2-x1
This formula is used to calculate simple interest, where I represents interest, P is the principal, r is the rate, and t is time.
What is Simple Interest I = PRT
The trend or direction that the data points follow on a scatterplot, often described as positive, negative, or none.
What is the correlation?
This type of number includes all integers, fractions, whole, natural, and irrational numbers
What is the set of real numbers?
This is a mathematical statement that shows two expressions are equal, typically written with an equals sign.
What is an equation?
A slope of 0 means the line is this.
What is a horizontal line?
This is a set amount of money you borrow or lend, often with interest, that must be repaid over time.
What is a loan?
A scatterplot showing a wide spread of points and no clear direction indicates this type of relationship between variables.
What is no correlation?
This is the set of all positive and negative whole numbers, including zero.
What are integers?
This term describes an equation that includes signs (like <, >, ≤, ≥) instead of an equals sign.
What is an inequality?
This type of slope occurs when a line is vertical.
What is an undefined slope?
What is the compound interest formula?
A= P(1+r)t
When data points on a scatterplot move in a straight line from lower-left to upper-right, this type of relationship is indicated.
What is a positive correlation?
What is the smallest subset that all of these numbers fit into?
0.5, 32, 716, -52, -0.05050505
What is Rational Numbers?
When solving the equation 3x+4=10, this is the first step you would take.
What is subtract 4 from both sides?
What is another word for slope?
What is the rate of change? rise/run
This term is money that a person can borrow against, typically from a bank or other financial institution.
What is credit?
This type of correlation is shown when the data points on a scatterplot form a downward trend, moving from upper-left to lower-right.
What is a negative correlation?
This subset of real numbers includes positive numbers, zero, and negative numbers that can be written as fractions.
What are rational numbers?
When solving the inequality 2x−3>7, you would first do this operation to isolate x.
What is add 3 to both sides?
steepness of a line.
What is the slope?
This is the money given to students based on financial need or merit, which does not need to be repaid.
What is scholarship or Grant?
The line or curve that best fits the data points in a scatterplot, often determined by using a statistical method like least squares.
What is a line of best fit?
