Answer:

               -\dfrac67

Step-by-step explanation:

slope of r:

                  a_r=\dfrac{10-3}{8-2}=\dfrac76

s is perpendicular to r:

s\perp r\ \ \implies\ \ a_s\cdot a_r=-1\\\\a_s\cdot\dfrac76=-1\\\\a_s=-\dfrac67

Find the gradient of the line passing through (6,8) and (4,10)
Mariulka [41]

Question:

Find the gradient of the line passing through (6,8) and (4,10).

Answer:

-1 is the right answer.

Step-by-step explanation:

Slope of the line = The gradient of the line

Gradient of the line is known as change in the value of y-axis by change in the value of x-axis

Gradient = ∆y\∆x

Gradient = \frac{y_ 2 - y_1}{x_2 - x_1}  =  \frac{(10 - 8)}{(4 - 6)}  =  \frac{(2)}{(- 2)} =\boxed{- 1}\\

The circle shown below has AB and BC as its tangents: AB and BC are two tangents to a circle which intersect outside the circle
Nadusha1986 [10]
We are given with
arc AC = 130
The measure of the arc on the other side of the circle is
360 - 130 = 230
Therefore, according to the theorem on circles, the measure of angle ABC is 
(1/2) ( 230 - 130) = 50
