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.

Answer:

See attachment for graph

Step-by-step explanation:

Given

[tex]y = 0.75x + 9.25[/tex]

Required [Missing from the question]

Graph the equation

First, we determine two points that satisfy the equation.

Let: [tex]x = 1[/tex]

[tex]y = 0.75x + 9.25[/tex] becomes

[tex]y = 0.75*1 + 9.25 = 0.75 + 9.25 =10[/tex]

This point will be represented as:

[tex](1,10)[/tex]

Let: [tex]x = 5[/tex]

[tex]y = 0.75x + 9.25[/tex] becomes

[tex]y = 0.75 * 5 + 9.25 = 3.75 + 9.25 = 13[/tex]

This point will be represented as:

[tex](5,13)[/tex]

So, we plot: [tex](1,10)[/tex] and [tex](5,13)[/tex]
