The answer is definitely a
you have to find the scale factor by its length
how to : scale factor = dimension of the new shape ÷ dimension of the original shape
but if it is scaled then do
scale factor = larger figure dimensions ÷ smaller figure dimensions
Answer:
2
Step-by-step explanation:
Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:

That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.
For example,

and

would work, but so would
