Answer:
(7, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 14 → (1)
y = 2x - 14 → (2)
Since both equations express y in terms of x we can equate them
2x - 14 = - 2x + 14 ( add 2x to both sides )
4x - 14 = 14 ( add 14 to both sides )
4x = 28 ( divide both sides by 2 )
x = 7
Substitute x = 7 into (2) for corresponding value of y
y = (2 × 7) - 14 = 14 - 14 = 0
Solution is (7, 0 )
From the equation we see that the center of the circle is at (-2,3) and the radius is 9.
So using the distance formula we can see if the distance from the center to the point (8,4) is 9 units from the center of the circle...
d^2=(8--2)^2+(4-3)^2 and d^2=r^2=81 so
81=10^2+1^2
81=101 which is not true...
So the point (8,4) is √101≈10.05 units away from the center, which is greater than the radius of the circle.
Thus the point lies outside or on the exterior of the circle...

The slope is the gradient
Gradient = rise/run
Gradient = -1/1
Gradient = -1
Slope = -1
