Answer:
5
Step-by-step explanation:
x²-6x+y²+4y+13=0
or, x²-6x+y²+4y+9+4=0
or, x²-6x+9+y²+4y+4=0
or, (x²-2.3.x+3²)+(y²+2.2.y+2²)=0
or, (x-3)²+(y+2)²=0
Square of two positive terms is 0
x-3=0
x=3
and
y+2=0
y=-2
so,
x-y=3+2
=5

Answer:
Q(2, 6 )
Step-by-step explanation:
Using the midpoint formula
let the coordinates of Q = (x, y ), then
0.5(x + 10) = 6 ( multiply both sides by 2 )
x + 10 = 12 ( subtract 10 from both sides )
x = 2
and
0.5(y + 6) = 6 ( multiply both sides by 2 )
y + 6 = 12 ( subtract 6 from both sides )
y = 6
Coordinates of Q = (2, 6 )
Answer:
y=4x+9
Step-by-step explanation:
The slope intercept form is ![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
So m=4 and we plug it into the equation ![y=4x+b](https://tex.z-dn.net/?f=y%3D4x%2Bb)
Since there are x point is -1 and y point is 5 we plug those in replacing the corresponding variables ![5=4(-1)+b](https://tex.z-dn.net/?f=5%3D4%28-1%29%2Bb)
So the equation becomes ![5=4+b](https://tex.z-dn.net/?f=5%3D4%2Bb)
We add 4 to both sides
so 9 equals b
Then we rewrite the whole equation as ![y=4x+9](https://tex.z-dn.net/?f=y%3D4x%2B9)
