8x-6(-6x+4) = 8x+36x-24= 44x-24
Is there more to the question?
Since you didn't provide the points, we can't find the exact answer. However, I can explain how to do the problem for you.
To test the point, just plug in the x and y values and see it the statement is true or false.
Let's try: (3, 4)
Plug in the points and evaluate:
2(4) = 2 + 3
8 = 6
FALSE
Since this is a false statement, then the point is not on the line.
The square root of six hundred and twenty-five √625 = 25
