Answer:
option C

Step-by-step explanation:
The point slope equation of a line is given by

Where m is the slope and (x1,y1) is the point on the point

We need to write the equation in y=mx+b form
multiply -2/3 inside the parenthesis

Subtract 7 from both sides

Both mean to factor, I've never heard of a difference
Answer:
-3
Step-by-step explanation:
There's a three point distance between the two on a coordinate plane
can be simplified as 5-9+7=-4+7=3
