Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter
Answer:
The equation of line in the form of Ax + By = C is:
Step-by-step explanation:
We need to find the equation of line, with the given slope passes through the given point.
Slope m = -4
Point: (-2,-9)
We need to find slope and y-intercept of the line.
The slope of line is given m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, we can find y-intercept
The formula used will be:
Putting values of: y= -9, x =-2 and m = -4
So, y-intercept b = -17
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:
Writing equation in required form i.e. of Ax + By = C
So, the equation of line in the form of Ax + By = C is:
