1. The slope is the number that is multiplied by X, since the slope is -1, when multiplied by X you would get -X, the y intercept is the given y coordinate (5), so the equation would be y = -x+5


2. Replace f(h) with 225 and solve for h:

225 = 15h +75

Subtract 75 from each side:

150 = 15h

Divide both sides by 15:

h = 10 hours


3.  4x + 2y = -2

subtract 4x from each side"

2y = -4x - 2

Divide both sides by 2:

y = -4x-2 / 2

y = -2x -1
