12/14 can be simplified, and that would be an equivalent ratio. Divide 12 and 14 both by 2, and then you get 6/7.
Another equivalent ratio is 120/140. To get this ratio, I merely multiplied both the numerator and denominator of the ratio by 10.
You can get an infinite amount of equivalent ratios for 12/14. All you have to do is make sure that whatever you multiply one part of the ratio by, you have to multiply the other part of the ratio by the same thing.
A final example is 60/70. I just multiplied both 12 and 14 by 5.
The system of equation that has one solution is: (d) –2x+ 7y = –5 and 2x +7y = –9
<h3>What are systems of equations?</h3>
This is a group of equations which may have none, one or more solutions.
From the list of given options, the system of equations that has one solution is:
–2x+ 7y = –5 and 2x +7y = –9
This is so because, the solution is (-1,-1)
However, the other systems have infinite many solutions

Answer:
x-int=-8, y-int=2,-4
Step-by-step explanation:
for the x-int
you set x to 0 then solve the equation to get -8
for the y-int
you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4
