Answer:
it's b
Step-by-step explanation:
it's b because the lines outside of the equation mean the absolute value of the equation
y-intercept: Let x = 0 and solve for y:
(x-1)^2 + (y-2)^2 = 10 => (-1)^2 + y^2 - 4y + 4) = 10
=> 1 + y^2 - 4y + 4 = 10, or y^2 - 4y -5 = 0
The solutions of this quadratic are y = 5 and y = -1.
Thus, the y-intercepts are (0, 5) and (0, -1).
Now find the x-intercepts: Let y = 0 and solve the resulting equation for x:
(x-1)^2 = 10 - (-2)^2, or (x-1)^2 = 10 - 4 = 6.
Taking the sqrt of both sides, x - 1 = plus or minus sqrt(6), or:
x = 1 +√6 and x = 1 - √6, so that the x-intercepts
are (1+√6, 0) and (1-√6, 0).
A(-1,3), B(-2,5)
Slope equation : (y₂-y₁) / (x₂-x₁)
Plug in the values into the equation.
AB = (5 - 3) / (-2+1)
Simplify.
AB = 2 / -1
AB = -2
So, your slope is -2.
