Answer:
45 degrees
Step-by-step explanation:
90 degrees
Hope this helps
We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).
Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2
Slope is 2.
From what you said the choices go up by 3 every time in different combinations . Its at least 36 or more combinations .
i did my best guess from the choice .. hope it helps
Circle formula
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center
and r=radius
to find the radius
we are given one of the points and the center
distnace from them is the radius
distance formula
D=
![\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28x2-x1%29%5E%7B2%7D%2B%28y2-y1%29%5E%7B2%7D%7D%20)
points (-3,2) and (1,5)
D=
![\sqrt{(1-(-3))^{2}+(5-2)^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%281-%28-3%29%29%5E%7B2%7D%2B%285-2%29%5E%7B2%7D%7D%20)
D=
![\sqrt{(4)^{2}+(3)^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%284%29%5E%7B2%7D%2B%283%29%5E%7B2%7D%7D%20)
D=
![\sqrt{16+9}](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%2B9%7D%20)
D=
![\sqrt{25}](https://tex.z-dn.net/?f=%20%5Csqrt%7B25%7D%20)
D=5
center is -3,2
r=5
input
(x-(-3))^2+(y-2)^2=5^2
(x+3)^2+(y-2)^2=25 is equation
radius =5
input -7 for x and solve for y
(-7+3)^2+(y-2)^2=25
(-4)^2+(y-2)^2=25
16+(y-2)^2=25
minus 16
(y-2)^2=9
sqqrt
y-2=+/-3
add 2
y=2+/-3
y=5 or -1
the point (-7,5) and (7,-1) lie on this circle
radius=5 units
the points (-7,5) and (-7,1) lie on this circle
