You can put this solution on YOUR website!
You need two points on the line in order to graph it.
\n" ); document.write( "Plug-in two different x values in the equation to get their y values, like so:
\n" ); document.write( "---
\n" ); document.write( "Point p1, use x=0:
\n" ); document.write( "y = 3(0) - 2
\n" ); document.write( "y = -2
\n" ); document.write( "p1 = (0, -2)
\n" ); document.write( "---
\n" ); document.write( "Point p2, use x=1:
\n" ); document.write( "y = 3(1) - 2
\n" ); document.write( "y = 1
\n" ); document.write( "p2 = (1, 1)
\n" ); document.write( "---
\n" ); document.write( "Now draw a line between points p1 and p2 to graph the equation.
\n" ); document.write( "The line extends infinitely beyond both points.
\n" ); document.write( "---
\n" ); document.write( "To check the answer, calculate the slope from the two points, like so:
\n" ); document.write( "Calculate slope: m = (y2 - y1)/(x2 - x1)
\n" ); document.write( "m = (1 - -2) / (1 - 0)
\n" ); document.write( "m = 3 / 1
\n" ); document.write( "m = 3
