Algebra: Write a Linear System

Write systems of two linear equations given a graph or a verbal description. Based on TEKS standard A.2(I). Made in cooperation with Mathy Cathy!

What is a linear system?

Two or more linear equations with the same variables One linear equation with two variables Lines graphed together on the same coordinate plane The steepness of a line
Which system of linear equations is best represented by this graph?

? = 2? − 4 and ? = ? + 8 ? = −2? − 4 and ? = ? + 8 ? = −2? + 4 and ? = ? + 8 ? = 2? − 4 and ? = ? − 8
Which pair of equations corresponds to the lines shown?

? = ? + 4 and ? = ? ? = ? − 4 and ? = −? ? = ? + 4 and ? = −? ? = −? + 4 and ? = −?
