Slope is a number in front of x, so slope is (-2)
y-y1=m(x-x1)
y-5= -2(x+5)
y-5= -2(x-(-5))
so y1=5, x1=-5, a point is (x1,y1), so the point is (-5,5)
Archimedes is the father of mathematics.
Answer:
Radius = 5
center is (19,-1)

Step-by-step explanation:
Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.
Distance between the points is calculated using formula


diameter = 10
radius = diameter divide by 2
Radius = 5
midpoint is the center of the circle


(19,-1)
Equation of the circle

h,k is the center and r is the radius
h=19 and k=-1 , r=5
