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.
1) the answer is D because 3 × 3 = 9 - (-1) = 10 cause we do Keep, Change, Change. You keep the 9, change the minus ( - ) sign into + (addition) and change -1 into 1. 3) i think its a or d :)
