We can use the formula y2-y1/x2-x1 to find our answer. So, we have : t-16/5-2 = -3. We simplify that to t-16/3 = -3. We can then multiply both sides by 3 to get t-16 = -9. Then we can add 16 to both sides to get t = 7.
Well since I do not know the unit of measure, I can not give you the answer in a unit of measure but it would be the same answer just add the unit for example meter at the end of the answer and square it. The answer is: 232.048
