General formula to determine the equation of the liney - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope
Find the slopeGiven:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)
We could find the slope by using this formula
m =
Plug in the numbers
m =
m =
m =
m = 7
The slope is 7
Determine the line equationPlug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!
