Answer:
Step-by-step explanation:
they have given you three points P1 , P2 and P3. We only need two of them, any two will work
P1= (x1, y1) = (-1,8)
P2=(x2,y2) = (3,-4)
now use the slope formula to find the slope , use the variable 'm' for slope since that a very commonly used variable letter for slope
m = ( y2 - y1 ) / ( x2 - x1 )
m = (-4 - 8 ) / ( 3 - (-1) )
m = (-12) / 3 + 1 )
m = -12 / 4
m = - 3
there is your slope, got it? send a note if you have other questions :)
Given:
The x and y axis are tangent to a circle with radius 3 units.
To find:
The standard form of the circle.
Solution:
It is given that the radius of the circle is 3 units and x and y axis are tangent to the circle.
We know that the radius of the circle are perpendicular to the tangent at the point of tangency.
It means center of the circle is 3 units from the y-axis and 3 units from the x-axis. So, the center of the circle is (3,3).
The standard form of a circle is:
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting , we get
Therefore, the standard form of the given circle is .
