Answer:
(2,-2)
Step-by-step explanation:
The minimum is the vertex, which is (x,y). The x-coordinate is listed first, the y-coordinate second. The x-coordinate is 2 and the y-coordinate is -2, making the minimum (2,-2)
Answer:
13- A 14-B
Step-by-step explanation:
You take the formula (x1+x2/2, y1+y2/2) and plug in accordingly. For instance, when you plug the values in for 13, you would get:
x1+-9/2, y1+7/2= -8,2
All you have to do from there is a simple guess and check or plug in each number from the multiple answer choices you have. You should then get A (-7,-3) Do the same with 14, in which you should get B (11,-20)
