trying to find the slope-intercept form that passes thru these given points (-3,-3) (1,9)
\n" ); document.write( "***
\n" ); document.write( "slope-intercept form of equation for a line: y=mx+b, m=slope, b=y-intercept
\n" ); document.write( "for given problem:
\n" ); document.write( "slope,m=∆y/∆x=(9-(-3))/(1-(-3))=(9+3)/(1+3)=12/4=3
\n" ); document.write( "equation: y=3x+b
\n" ); document.write( "solve for b using coordinates from one of the given points,(1,9), on the line
\n" ); document.write( "9=3*1+b
\n" ); document.write( "b=6
\n" ); document.write( "equation: y=3x+6
\n" ); document.write( "
