Answer:
Slope - intercept form
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given points are ( -9 ,-8 ) and (-6,6)
slope of given two points
The equation of the straight line passing through the points and having slope
3 y + 2 4 = 14 x + 126
3 y = 14 x + 126 - 24
3 y = 14 x + 102
Slope - intercept form y= mx +C
Slope - intercept form
Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides
r=5
