Overview The rate of change is a ratio that compares the change in values of the y variables to the change in values of the x variables. If the rate…
read moreOverview A linear function follows the standard form ax + by = c. The intercepts are the points where the line intersects each axis. A line can be graphed by…
read moreOverview In order for functions to be linear, they must follow two criteria. First, each domain value must be paired with one range value. If a domain value is paired…
read moreOverview Arithmetic sequences are sequences in which the difference between one term and the next term is a constant amount. They can be defined by developing a rule that relates…
read moreOverview Data in real-world situations doesn’t always fall into neat linear relationships. The actual values may be plotted in a scatterplot. Trend lines approximate the direction and size of the…
read moreOverview A function is a special relationship between variables in an equation such that for every domain value, there is only one range value. Functions can be expressed using a…
read moreOverview Relationships between data points can often be represented on graphs. They can also be expressed in ordered pairs as relations or functions. Relationships and Graphs One of the many…
read moreOverview Compound inequalities are similar to compound statements, as they are two simple inequalities joined by conjunctions. Suppose it were true that a variable x was between 2 and 9.…
read moreOverview If an inequality contains more than one operation, it will take more than one step to solve it. Suppose that in order to solve an inequality, both multiplication and…
read moreOverview While equations are statements that two quantities are equal, inequalities state that quantities are not equal. One side of the expression might be greater than the other side, or…
