Answer:

Step-by-step explanation:

A graph representing direct variation must pass through the origin (0, 0)

Thus the grid passing through (- 2, 1), (0, 0) and (2, - 1)

Answer:

g = 7 1/3

Step-by-step explanation:

Add 5 to both sides so it cancels out. 3g = 22
Divide both sides by 3. g = 7.333...

7.333... and 7 1/3 are equivalent, so just put either one.

The diagram shows the rectangle ABCD, where A is (3,2) and B is (1,6).

In-s [12.5K]

(i)
$A(3,2),B(1,6)
\\
\\m_{AB}= \frac{6-2}{1-3}=-2
\\
\\m_{BC}m_{AB}=-1
\\ 
\\m_{BC}= \frac{-1}{m_{AB}} = \frac{-1}{-2}= \frac{1}{2} 
\\
\\B(1,6)\Rightarrow x_1=1,y_1=6
\\
\\BC:y-y_1=m_{BC}(x-x_1)
\\
\\y-6= \frac{1}{2}(x-1)
\\
\\2y-12=x-1
\\x-2y+11=0$

(ii)
$AC:y=x-1
\\BC:x-2y+11=0
\\
\\C=AC\cap BC
\\
\\x-2(x-1)+11=0
\\x-2x+2+11=0
\\x=13
\\y=x-1=13-1=12
\\C(13,12)$

(iii)
$A(3,2)B(1,6),C(13,12)
\\P=2(d(A,B)+d(B,C))
\\
\\d(A,B)= \sqrt{(1-3)^2+(6-2)^2}= \sqrt{20} =2 \sqrt{5} 
\\
\\d(B,C)= \sqrt{(13-1)^2+(12-6)^2}= \sqrt{180}= 6\sqrt{5} 
\\ 
\\P=2(2 \sqrt{5}+6 \sqrt{5})=2\times8 \sqrt{5} =16 \sqrt{5}$
