first find slope of 4x3y = 12 y = 4/3 x + 12 so slope is 4/3 and this is also the slope of the reqd line as they are parallel use general form: yy1 = m(xx1) where m = slope and a point on line is (x1,y1) so y4 = (4/3) (x  (3)) y  4 = (4/3)x + 4 multiply through by 3 3y  12 = 4x + 12 3y  4x = 24 is the equation you want

you can check this out by plugging in x = 3 , y = 4: 3(4)  4(3) = 12 + 12 = 24

and if you rearrange the equation 3y = 4x + 24 y = (4/3) x + 8  so the slope = 4/3
