Answer: 2
Description. Create a line from point A perpendicular to the x axis. This line, with the radius (OA) , and x axis, form a right triangle. By Pythagoras,
x-length y-length hypotenuse squared
( 3 ^ (1/2) ) ^ 2 + 1 ^ 2 = 3 + 1 = 4
So, the square of the hypotenuse (or radius OA in this case) is 4. That means OA is the square root of 4 or 2.

We can see that
The given points are on same line.
Further explanation:
There are two methods to find if the given points are on same line
- The slope method: If the points are on same line the slopes of two pairs of points will be same
- Area of triangle method
Given points are:
A(1,3) B(4,2) C(-2,4)
We will find the slope of AB, BC, and AC
So,
We can see that
The given points are on same line.

Answer:
two solutions : (-3;4) and (-5;6)
Step-by-step explanation:
hello :
X²+y²+18x+29=0 ..(1)
X+y=1 ...(2)
by (2) : y = 1 - x
put this value in (1) : x² +(1-x)² +18x+29 = 0
x² +1 +x² -2x+18x +29 =0
2x²+16x +30 = 0
x²+8x+15 =0
delta = b²-4ac a=1 b=8 c = 15
delta = (8)²-4(1)(15)=64-60 =4 = 2²
X1=(-8+2)/2 = - 3
X2=(-8-2)/2 = - 5
case 1 : x = -3 y = 1 - (-3) = 4
case 2 : x = -5 y = 1 - (-5) = 6
