\nAn equation whose graph is a straight line is called a linear equation.<\/p>\n
\nReasoning If the points (+<\/sup>1, +<\/sup>7), (+<\/sup>1, +<\/sup>3), (+<\/sup>1, –<\/sup>5), and (+<\/sup>1, –<\/sup>9) were graphed, they would form a vertical line. Do you think the equation for this line would be x = +<\/sup>1 or y = +<\/sup>1? Explain.
