Answer:
(-1,-2)
Step-by-step explanation:
There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.
x= -1
y=3x+1
y= 3(-1)+1
y= -3+1
y= -2
Plugging y value in the equation to find x:
-2=3x+1
-3=3x
x= -1
Therefore, the point is (-1,-2)

Answer:
Step-by-step explanation:
The center of the circle whose diameter has endpoints (18, -13) and (4, -3) will be the midpoint of the coordinates.
The ormua for calculating mid point is expressed as;
M(X,Y) ={(x21+x2/2, y1+y2/2}
X= x1+x2/2
Y = y1+y2/2
From the coordinates
x1 = 18 x2 = 4
X= 18+4/2
X = 22/2
X = 11
y1= -13, y2= -3
Y = -3-13/2
Y = -16/2
Y = -8
Hence the required centre will be at (11,-8)
