Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
2.500.000 is the answer but I think simplifying it would make it 2.5?
So firstly, add both sides by 6: 
Next, multiply both sides by 4, and your answer will be 
X = - 4; y = 3; z = 2;
2 x² - 2 z^4 + y² - x² + z^4 =
= 2 * (-4)² - 2 * 2^4 + 3² - ( -4)² + 2^4 =
= 2 * 16 - 2 * 16 + 9 - 16 + 16 =
= 32 - 32 + 9 - 16 + 16 = 9
