Algebra 1 PARCC question: rational-irrational

When multiplying rational and irrational numbers, what do you get as a product? Well, it's not such a straightforward answer.

Algebra 1 PARCC question: factor to solve

You should be able to factoring a quadratic expression by the time you finish algebra 1. Drop-down menus limit your options on the test.

Algebra 1 PARCC question: table rate of change

The average rate of change can be calculated for a linear relationship between 2 quantities using a table of values.

Algebra 1 PARCC question: graph of function

The graph of a quadratic function is continuous; the domain is all real numbers, except in a few very special circumstances.

Algebra 1 PARCC question: rewrite formula

The PARCC test in algebra 1 will require you to be able to rewrite formulas by algebraically rearranging them to solve for the variable of interest.

Algebra 1 PARCC question: rate of change

In word problems, we compute the rate of change, the cost per pound, the number of cats we just have to buy, and lots of other quantities.

Algebra 1 PARCC question: multiply binomials

You can use the FOIL method to multiply 2 binomials. It works for certain cases, but learning how to apply the distributive property is better.

Algebra 1 PARCC question: graph y=mx+b

It's possible to estimate the solution to a system of linear equations by graphing them on a coordinate plane. Here's PBA #4.

Algebra 1 PARCC question: quadratic zeros

It's possible to find the zeros of a quadratic function (a parabola) by factoring it, provided there are real zeros for the function.

Algebra 1 PARCC question: linear functions

How do you spot a "linear function" when given a table of values, a graph, a word problem, or an equation?
