Algebra 1 PARCC: points on a line

0
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.

Algebra 1 PARCC: find real zeros

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

Algebra 1 PARCC question: exponential websites

0
Modeling real-world situations sometimes requires a linear model, sometimes an exponential model, sometimes a coffee model.

Algebra 1 PARCC question: compare job offers

0
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.

Algebra 1 PARCC question: graph Ay + Bx = C

0
We have lots of equivalent ways of writing equations for lines, or linear functions, including slope-intercept, point-slope, and Ax+By=C.

Algebra 1 PARCC question: predict from data
