Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
where 'k' is the proportionality constant.
From table (1),
Therefore, relationship is not proportional.
From table (2),
![\frac{1}{6}=\frac{3}{18}=\text{constant}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%3D%5Cfrac%7B3%7D%7B18%7D%3D%5Ctext%7Bconstant%7D)
True.
So the relationship will be proportional.
From table (3),
![\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bhours%7D%7D%7B%5Ctext%7BMiles%7D%7D%3D%20%5Cfrac%7B2%7D%7B110%7D%3D%5Cfrac%7B5%7D%7B175%7D%3D%5Cfrac%7B1%7D%7B55%7D)
Which is constant.
Therefore, relationship will be proportional.
From table (4),
![\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BHours%7D%7D%7B%5Ctext%7BPaid%7D%7D%3D%5Cfrac%7B3%7D%7B29.25%7D%3D%5Cfrac%7B5%7D%7B48.75%7D%3D0.103)
Which is constant for every term.
Therefore, relationship will be proportional.
Answer:
P=7
Step-by-step explanation:
7-3=4
4/2=2
therefore,
p=7
Should be C
because 1/2u = (-0.5, 2)
so its (-0.5,2)-(3,-2)
which is
-0.5 - 3 = -3.5
2 - - 2 = 4

Answer:
7) ![y = - \frac{5}{3}x](https://tex.z-dn.net/?f=y%20%3D%20-%20%5Cfrac%7B5%7D%7B3%7Dx)
8) ![y = \frac{1}{2}(3x - 1)](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%283x%20-%201%29)
Step-by-step explanation:
7) The equation of the straight line passing through the ordered pair (-3,5) and (3,-5) is given by
![\frac{y - 5}{5 - (- 5)} = \frac{x - (- 3)}{- 3 - 3}](https://tex.z-dn.net/?f=%5Cfrac%7By%20-%205%7D%7B5%20-%20%28-%205%29%7D%20%3D%20%5Cfrac%7Bx%20-%20%28-%203%29%7D%7B-%203%20-%203%7D)
⇒ -3(y - 5) = 5(x + 3)
⇒ -3y + 15 = 5x + 15
⇒ 5x + 3y = 0
⇒
(Answer)
8) The equation of the straight line passing through the ordered pair (5,7) and (11,16) is given by
![\frac{y - 7}{7 - 16} = \frac{x - 5}{5 - 11}](https://tex.z-dn.net/?f=%5Cfrac%7By%20-%207%7D%7B7%20-%2016%7D%20%3D%20%5Cfrac%7Bx%20-%205%7D%7B5%20-%2011%7D)
⇒ 2(y - 7) = 3(x - 5)
⇒ 2y - 14 = 3x - 15
⇒ 3x - 2y - 1 = 0
⇒
