H - 20 = 1/2(H - 24) + 13

Pls help me

Consider the function f(x)=-5x+3 what is f(-2)

An object is translated by (x + 4, y - 2). if one point in the image has the coordinates (5, -3), what would be the coordinates of its pre-image? (9, -5) (1, -5) (9, -1) (1, -1)

Ithink i know it but i want to be sure so can you me out ?
