To mail a letter to Vienna, Austria the post office charges a flat rate of $9.25 and an additional $0.75 for every ounce the letter weighs. The cost of mailing a letter is determined by the equation y=0.75x+9.25, where y is the cost of the postage and x is the weight of the letter in ounces.

Step-by-step explanation:

Given

$y = 0.75x + 9.25$

Required [Missing from the question]

Graph the equation

First, we determine two points that satisfy the equation.

Let: $x = 1$

$y = 0.75x + 9.25$ becomes

$y = 0.75*1 + 9.25 = 0.75 + 9.25 =10$

This point will be represented as:

$(1,10)$

Let: $x = 5$

$y = 0.75x + 9.25$ becomes

$y = 0.75 * 5 + 9.25 = 3.75 + 9.25 = 13$

This point will be represented as:

$(5,13)$

So, we plot: $(1,10)$ and $(5,13)$
