Lol can someone me on #'s 1 and 3 i'm confuzzled as ever lol

1. You can solve this by substituting in each value of x and y and seeing if the equation works. I did this, and found that the answer was D because 3 × 3 = 9, and 9 - -1 = 10.

3. The formula for finding the slope from two points is (y2 - y1)/(x2 - x1). When you use the values, you get (4 - 3)/(-3 - 5) which simplifies into 1/-8 which is answer A.

I hope this helps!
