Measures of central tendency and the spread of data, including outliers, will come into play as students take the PARCC test in algebra 1 this spring.

Solving equations for a variable of interest is required in algebra 1 on the PARCC test (and in the Common Core). Students find the radius of a circular pool.

Is a given ordered pair on the graph of a function? Algebra 1 students should be able to figure it out, esp. those who will take the PARCC test this year.

The zeros of a polynomial are the *x* values when the polynomial equals 0. Do you know how to find the zeros?

Modeling real-world situations sometimes requires a linear model, sometimes an exponential model, sometimes a coffee model.

The point at which something more expensive to buy becomes less expensive because operating costs aren’t as high can be modeled with a system of linear equations.

We have lots of equivalent ways of writing equations for lines, or linear functions, including slope-intercept, point-slope, and Ax+By=C.

You can find the average of a set of data and use it to model the behavior of a system that is under investigation in the real world.

We complete the square here, to solve a quadratic equation. Also, the question provides some useful tips about the solutions to quadratic equations.
