Algebra.Com's Answer #287339 by robertb(5830)![]() ![]() You can put this solution on YOUR website! The slope of y = x is 1, and the y-intercept is 0. Fixing the value of the slope to 1, if we change the y-intercept to b > 0, then the x-intercept becomes -b <0. \n" ); document.write( "Changing the y-intercept to b < 0, the x-intercept becomes -b > 0. \n" ); document.write( "Hence if we increase the y-intercept, there is a corresponding DECREASE in the x-intercept (in the same numerical amount.) If we decrease the y-intercept, there is a corresponding INCREASE in the x-intercept (in the same numerical amount.) \n" ); document.write( " |
