Answer: Yes A is correct
Step-by-step explanation:
Multiply the first equation by 3...
2x+3y=k+1 needs to be subtracted by 3x+3y=3k
which equals -x=-2k-1
Then you can multiply the equation by -1 to make them all positive. Resulting in x=2k+1
Given the following question:
Point A = (7, 4) = (x1, y1)
Point B = (3, 6) = (x2, y2)
To find the slope use rise over run:

m = -0.5
