(-3,-2)
\n" ); document.write( "(-1,0)
\n" ); document.write( "(1,2)
\n" ); document.write( "if you were to connect these points with a line, where would the y-intercept be located?
\n" ); document.write( "---------------
\n" ); document.write( "Pick a couple of points and find the equation of the line thru them.
\n" ); document.write( "Using (1,2) and (-1,0)
\n" ); document.write( "---------------
\n" ); document.write( "slope = [2-0]/[1--1] = 2/2 = 1
\n" ); document.write( "-------------
\n" ); document.write( "Form y=mx+b
\n" ); document.write( "Substitute to find \"b\":
\n" ); document.write( "2 = 1*1+b
\n" ); document.write( "b = 1
\n" ); document.write( "EQUATION: y = x+1
\n" ); document.write( "--------------------------
\n" ); document.write( "The y-intercept is (0,1)
\n" ); document.write( "======================
