<u>ANSWER</u>
<u>EXPLANATION</u>
The equation of the circle in general form is given as:
To obtain the standard form, we need to complete the squares.
We rearrange the terms to obtain:
Add the square of half the coefficient of the linear terms to both sides to get:
Factor the perfect square trinomial and simplify the RHS.
This is the equation of the circle in standard form.
<u><em>Seventy-seven is a composite number. </em></u>
Because you had to divide by eleven or seven. Then you can multiply by seven or eleven its equal to seventy-seven.

Answer:
(x, y) = (3, 5)
Step-by-step explanation:
To solve these equations graphically, you plot each one, then identify the coordinates of the point of intersection.
The first equation can be graphed using the y-intercept of -1 and the slope of 2.
The second equation has a y-intercept of 18/3 = 6, and a slope of -1/3. The x-intercept of 18 is off the chart, so the slope and intercept are a good way to plot this line, too.
__
The slope is the "rise" divided by the "run". A slope of 2 means the line goes up 2 units for each unit to the right. A slope of -1/3 means the line goes down 1 unit for each 3 units to the right.
The solution is (x, y) = (3, 5).
