What is the equation of the transformation of y=x^2, up 4 units and right 2 units?

  y = (x -2)^2 +4

Step-by-step explanation:

Translation (right, up) by (h, k) gives you the function ...

  g(x) = f(x -h) +k

You want f(x) = x^2 to be translated right 2 and up 4, so it becomes ...

  y = (x -2)^2 +4

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
