Unit 2 Overview and Readiness
We connect the points with a straight line to get the graph of the equation.
Practice this chapterWe connect the points with a straight line to get the graph of the equation. A graph is a visual representation of all the solutions of the equation.
An ordered pair ( x , y ) is a solution of the linear equation A x + B y = C , if the equation is a true statement when the x - and y -values of the ordered pair are substituted into the equation Linear equations have infinitely many solutions.
equation — a true statement when the x - and y -values of the ordered pair are substituted into the equation. graph — a visual representation of all the solutions of the equation.
Worked example
What does “equation” mean in Unit 2 Overview and Readiness?
- 1Use the wording this chapter gives for equation.
- 2The book says: a true statement when the x - and y -values of the ordered pair are substituted into the equation.
- 3Do not use the meaning of graph. That term means a visual representation of all the solutions of the equation.
Result: a true statement when the x - and y -values of the ordered pair are substituted into the equation
Why. That is the meaning this chapter gives for equation.
Do not swap equation and graph. equation means a true statement when the x - and y -values of the ordered pair are substituted into the equation. graph means a visual representation of all the solutions of the equation.
