Suppose we have a generic equation of the form:
1) The first thing you must do to complete squares is to group similar terms of the form:
2) The second step is to complete the squares.
3) The third step is factor the quadratic equation
4) The fourth step is to identify the center and the radius
Answer:
the first step in finding the center of the circle by completing the square is:
C group like terms

Use y=mx+b It helped me so much
Answer:
The lines are parallel to each other.
To figure this out you need to use the formula: m = y2 - y1 / x2 - x1
m represents the slope of the line.
So for the first line:
m = 4 - 2 ÷ -5 - (-9)
m = 2 / 4
Simplify: m = 1 / 2
The slope of the first line is 1 / 2.
For the second line:
m = 6 - 4 ÷ 1 - (-3)
m = 2 / 4
Simplify: m = 1 / 2
So, you can see that the slopes of both lines are the same. When the slopes are the same, that means that the lines are parallel to each other. When the coordinates are the same, that means that the lines are the same. When the slopes are flipped to each other and have are the opposite sign (positive or negative), then the lines are perpendicular.
