Answer:
7x - y = 5
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in point- slope form and rearrange into standard form.
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 7 and (a, b) = (1, 2)
y - 2 = 7(x - 1) ← in point- slope form
y - 2 = 7x - 7 ( subtract y from both sides )
- 2 = 7x - y - 7 ( add 7 to both sides )
5 = 7x - y , that is
7x - y = 5 ← in standard form

Answer:
It is more convenient to fill up in the United States.
Step-by-step explanation:
We convert a US gallon to liters:
1 Gallon equals 3.78541 liters.
Therefore, 1 US Gallon costs (3.78541) x (1.29) = 4.8831789 Canadian dollars.
Now we convert the price of a US gallon in Canadian territory to US dollars:
4.8831789 * 0.79 = 3.85771133 US dollars.
Conclusion: A gallon purchased in the United States costs 2.58 US dollars, while a gallon in Canada is equivalent to 3.85771133 US dollars. This way it is more convenient to fill up in the United States.
