9x + 3y = -54
3y = -9x - 54
y = -(3x + 18)
Therefore, the y-intercept of this equation is y=-18.

-7x+9y = 54 9y = 7x+54 y = 7/9x+6 which is now in slope-intercept form
Since there are no given triplets, none of them!
x/3-y/4 = 0 => multiply all terms by 12 => 4x-3y = 0 x/2+3y/10 = 27/5 => multiply all terms by 10 => 5x+3y = 54 4x-3y = 0 5x+3y = 54 Add both equations together which will eliminate 3y: 9x = 54 Divide both sides by 9: x = 6 Substituting the value of x into 5x+3y = 54 and 4x-3y = 0 gives y a value of 8. Therefore: x = 6 and y = 8
54 + 560 + 90 = 704
