graph y = x + 3 and what is the y- intercept?
\n" ); document.write( "----
\n" ); document.write( "You need two points.
\n" ); document.write( "----
\n" ); document.write( "x-intercept = ?
\n" ); document.write( "Let y = 0
\n" ); document.write( "then x+3 = 0
\n" ); document.write( "and x = -3
\n" ); document.write( "---
\n" ); document.write( "So the x-intercept is (-3,0)
\n" ); document.write( "===================================
\n" ); document.write( "y-intercept = ?
\n" ); document.write( "Let x = 0
\n" ); document.write( "then y = 0+3
\n" ); document.write( "and y = 3
\n" ); document.write( "---
\n" ); document.write( "So the y-intercept is (0,3)
\n" ); document.write( "=====================================
\n" ); document.write( "Plot those two points and draw a line thru them to get:
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cx%2B3%29\"$
