x 2 + y 2 + a x + b y = c
x2 + y2 − 2x + 6y − 6 = 0
Steps:
x^2 + y^2 - 2x + 6y - 6 = 0
(x - 1)^2 + (y - (-3)^2=4^2
Which means...
Center = (1,-3)
Radius = 4
Or option B
Answer:
(a,a)
Step-by-step explanation:
Keep in mind that the vertical line represents the y axis and the horizontal line represents the x axis
We want to find the coordinates of C
We can do this by looking at the given coordinates and the axis..
We are given that B is at (0,a) and we are given that D is at (a,0)
Now looking at C, we can tell that C shares the same y value as B and the same x value as D
If B has a y value of a and D has an x value of a then C would have an x and y value of a
Hence C would be at (a,a)
Answer:
y = 4x + 6
Step-by-step explanation:
y = mx + b
y = 4x + b
-2 = 4(-2) + b
-2 = -8 + b
b = 6
y = 4x + 6
I,m not sure but I tried my best I think it's c
