Write an equation in slope-intercept form of the line that passes through the points: ( -1/2 , 4 ) , ( 6 , -1/3 ). \n" ); document.write( "** \n" ); document.write( "equation for a line: y=mx+b, m=slope, b=y-intercept \n" ); document.write( "slope=∆y/∆x=(-(1/3)-4)/(6-(-1/2))=(-13/3)/(13/2)=-2/3 \n" ); document.write( "equation: y=-2x/3+b \n" ); document.write( "solve for b using coordinates of point (-1/2,4) \n" ); document.write( "4=-2*(-1/2)/3+b \n" ); document.write( "4=1/3+b \n" ); document.write( "b=11/3 \n" ); document.write( "equation: y=-2x/3+11/3 \n" ); document.write( " |
