Algebra I: Understanding Solutions of Systems Using Tables and Graphs
by Texas Instruments

Published on February 15, 2011


Students represent and analyze mathematical situations and structures using algebraic symbols.

Key Steps

  • Image

    Students will understand how the solution of a system of two equations is represented graphically and in a table of values. They will first use the trace feature to estimate the intersection of the two equations.

  • Image

    Then students will set up the table and use it to find the x-value that produces the same y-value for both Y1 and Y2.

  • Image

    The intersect command will enable students to verify the coordinates of the solution they found using the table of values.
