Multiply each by the same constant and you'll get another ratio ie. 5/7 --> 10/14 --> 15/21
I do not think there are any. If you used -20 and 2, which would be close to 16, the sum would be 18.
<span>(-1/2)(4)(-2)(7y)(-1)
Just start multiplying!
-1/2 * 4 = -2
-2 * -2 = 4
4 * 7y = 28y
28y * -1 = -28y
Since that's not an option I suspect you're missing an x.</span>
This is a linear function. They vary directly with each other.
x increasing by 1 each time.
y increases by 4 each time.
I hope this helps!
