Assuming you meant to put (7,25), then the answer m = 2.
m is the slope of the line.
The slope is equal to the change in Y divided by the change in X, or rise over run.
So in each parentheses there’s an X part ( the first number before comma, in this case, that would be either 3 or 7) and a Y part ( the number after the comma, in this case, 17 or 25).
Here’s how to solve it:
m = (y2- y1)/(x2-x1)
m = 25 -(17)/7-(3)
m = 8/4
which you can simplify to
m = 2
I hope this helps.
