Option D is a linear equation, so it represents a direct linear variation.
Hope this helps!
Step-by-step explanation:
to find the x intercept make y =0
6x - 2(0) = 12
6x = 12
x= 2
x intercept (2,0)
to find y intercept make x=0
6(0) - 2y = 12
-2y = 12
0= 12 + 2y
-12 = 2y
y= -6
y intercept (0,-6)
Answer:

Step-by-step explanation:
<em>Hey there!</em>
Cross multiply the given info
60 = 8m
Divide both sides by 8
m = 7.5

The correct option is: B. 450
<u><em>Explanation</em></u>
Current value of the investment is
dollars and 30 years ago, the value of the investment was
dollars.
Suppose, the value of investment today is
times greater than the value of the investment thirty years ago.
So, the equation will be........

Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
