The answer is false, it is only true for postulates, not conjectures.
It is called the slope of the line
The correct answer is the last set of numbers
784 divide by 7 is 112 so answer 112
We have the expressions:




Now, with this we operate as follows:
a)


Then, the axis is x = -3 and the vertex (-3, 6)
b)


Then, the vertex is (2, 5) and the axis is x = 2.
c)

Then, the vertex is (2, -4) andd the axis is x = 2.
d)


Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
