Answer:
the system has a unique solution
Step-by-step explanation:
Start with an equation of a line in standard form,
![ax + by = c](https://tex.z-dn.net/?f=%20ax%20%2B%20by%20%3D%20c%20)
Solve it for y to put it into the slope-intercept form:
![by = -ax + c](https://tex.z-dn.net/?f=%20by%20%3D%20-ax%20%2B%20c%20)
![y = -\dfrac{a}{b}x + \dfrac{c}{b}](https://tex.z-dn.net/?f=%20y%20%3D%20-%5Cdfrac%7Ba%7D%7Bb%7Dx%20%2B%20%5Cdfrac%7Bc%7D%7Bb%7D%20)
The slope is -a/b.
Now look at your system of equations. The slope of the first equation is -a/b = -2/3. The slope of the second equation is -a/b = -6/5.
You have a system of two linear equations with two lines with different slopes, so the lines must intersect at a single point.
Answer: the system has a unique solution
