The table contains the proof of the theorem of the relationship between slopes and parallel lines. What is the missing statement for step 6?

D. The slope of AC = The slope of DF

Step-by-step explanation:

Given

Parallel lines AC and DF

Required

What is the missing statement for step 6?

The question seem incomplete; however one can deduce from the list of options that the requirement of the question is to state the condition for parallel lines;

Let and represent the slope of AC and DF resoectively

The condition for parallel line is such that

This implies that

the slope of AC = the slope of DF

From the list of given options, option D correctly answers the question

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

just go here

its what i use
