The answer is A
You would multiply the second equation by -2 to clear the 'y'.
This leaves -10x = 2B and 3x = A
When combining these we get -7x = A - 2B
Answer:
2/3
Step-by-step explanation:
When a line is parallel to another, it means that there are never going to be any solutions(they won't ever intersect each other.) To do so, the slope of the lines have to be the same. It doesn't matter what the y-intercept is.
So the slope of the second line is going to be the same as the first line: 2/3
