To mail a letter to Vienna, Austria the post office charges a flat rate of $9.75 and an additional $0.50 for every ounce the letter weighs. The cost of mailing a letter is determined by the equation y=0.50x+9.75, where y is the cost of the postage and x is the weight of the letter in ounces.

y=3x+4

step-by-step explanation:

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

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

y=3x+4
