derive a linear polynomial function(in point slope form) with this information:
\n" ); document.write( "y-intercept of 10, decreasing on [-2,-4] with a slope of -.5
\n" ); document.write( "i have tried to do it myself, but i could not figure out the x-intercept.
\n" ); document.write( "----
\n" ); document.write( "Form: y = mx + b
\n" ); document.write( "m is the slope = -0.5
\n" ); document.write( "b is the y-intercept = 10
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "y = -0.5x + 10
\n" ); document.write( "=================================
\n" ); document.write( "x-intercept ??
\n" ); document.write( "Let y = 0 and solve for \"x\";
\n" ); document.write( "0 = -0.5x + 10
\n" ); document.write( "0.5x = 10
\n" ); document.write( "x = 20
\n" ); document.write( "==============
