Midpoint is ( -1 9/2)
Pls mark brainliest if correct

Let's solve ~
Calculate discriminant :






Now, let's calculate it's roots ( x - intercepts )



So, the intercepts are :

and

1. 3,6
2. 5,6
3. 4,5
(branliest will be appreciated and thanks)
67+1=68. 54+14=68 their are more than that just subtract a number from it and use it
And you will find the answer
A: Speed is Independent as it can be anything with no restrictions. Gas mileage is dependent as it relies on the value of speed for its value to be decided.
B: The first letter of speed is "S" so it can represent the variable. The first letter of mileage is "M" so the variable can be represented by that letter. It really can be any letter.
C: no context
D: no context
