The correct answer is B. y + 1 = -1/5 (x + 2)

I got B by putting the numbers in point-slope form which is y - y1 = m ( x - x1 ) so I got: y + 1 = m ( x + 2 )

Then to find m(the slope) I knew if the slope was 5 it would be parallel to y=5x+3 so therefore -1/5 would be perpendicular to the line y=5x=3.

Hope that helps!!

Step-by-step explanation:

GIRL! You should add diagrams to these types of questions. It would really help

That 10cm does not mean point C is 10cm. It means the line AB is 10 cm in total.

And since point C is the midpoint, which means that point C cuts the line AB in half, that makes AC = 5cm
