It should be 2 but i’m not positive
Only the third one makes x=-1 true
Answer:
![m(x, y)=(\frac{7}{2} , -\frac{5}{2} )](https://tex.z-dn.net/?f=m%28x%2C%20y%29%3D%28%5Cfrac%7B7%7D%7B2%7D%20%2C%20-%5Cfrac%7B5%7D%7B2%7D%20%29)
Step-by-step explanation:
Midpoint of line segment is calculated as
-----------(1)
Here
![(x_1, y_1) = (12,2) \ \ and \ \ (x_2, y_2) = (-5, -7)](https://tex.z-dn.net/?f=%28x_1%2C%20y_1%29%20%3D%20%2812%2C2%29%20%5C%20%5C%20%20and%20%5C%20%5C%20%28x_2%2C%20y_2%29%20%3D%20%28-5%2C%20-7%29)
Substituting values in equation (1)
![m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )](https://tex.z-dn.net/?f=m%28x%2C%20y%29%3D%28%5Cfrac%7B12-5%7D%7B2%7D%20%2C%20%5Cfrac%7B2-7%7D%7B2%7D%20%29)
![m(x, y)=(\frac{7}{2} , -\frac{5}{2} )](https://tex.z-dn.net/?f=m%28x%2C%20y%29%3D%28%5Cfrac%7B7%7D%7B2%7D%20%2C%20-%5Cfrac%7B5%7D%7B2%7D%20%29)
1) (-4,0)lowest and highest x values
2) (2,3)lowest and highest y values
3) (-2,0] point where the graph is going down
5) x-intercept is (-3,-1)
