Algebra.Com's Answer #38255 by Lacey020991(49) ![]() You can put this solution on YOUR website! \n" ); document.write( "First put this equation into slope-intercept form. (y=) \n" ); document.write( "-3x - 4y = -12 ------add 3x to each side. \n" ); document.write( "-4y = 3x - 12 -------divide each side by -4 \n" ); document.write( " \n" ); document.write( "Your y-intercept is the last number in the slope-intercept equation. In this case it is 3. \n" ); document.write( "To find the x-intercept, the y point is 0. So you would fill in a 0 for the y value. \n" ); document.write( "-3x - 4y = -12 \n" ); document.write( "-3x - 4(0) = -12 -----fill in a zero for y \n" ); document.write( "-3x - 0 = -12 ---------(-4)times 0 is zero \n" ); document.write( "-3x = -12 -------------The 0 can be taken out. \n" ); document.write( "x = 4 ---------------divide by -3 and get 4 \n" ); document.write( ". \n" ); document.write( "y-intercept = 3 \n" ); document.write( "x-intercept = 4 \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Tip: If you didnt want to put your equation into slope-intercept form, then you could fill in a 0 for the x-value, to find the y-intercept and solve it that way like we did for the x-intercept. \n" ); document.write( ". \n" ); document.write( "To find the slope, m, you would need 2 point. You could use your intercepts for this \n" ); document.write( "X(4,0) \n" ); document.write( "Y(0,3) \n" ); document.write( "x1=4 ; y1=0 \n" ); document.write( "x2=0 ; y2=3 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "Hope this helped. If you need me to explain something better, just let me know. \n" ); document.write( " |
