Everything that go horizontally is 0 slope
I'm not good with any math that is above per algebra sorry.
Answer:
x = 
Step-by-step explanation:
Since l bisects PQ at M then M is the midpoint of PQ, hence
PM = MQ, that is
5x - 7 = 11 - 2x ( add 2x to both sides )
7x - 7 = 11 ( add 7 to both sides )
7x = 18 ( divide both sides by 7 )
x = 
Answer:
D. ABE =CBD by SSS.
Step-by-step explanation:
Given that AB = BD and BE = BC, the lengths of AE and CD are equal to each other. Hence, triangles ABE and BCD are congruent by SSS Theorem. The answer is D.
ANSWER
The required line is BC
EXPLANATION
We want to find the line that passes through

and has slope

Since the x-value of the given point is zero, the point

is the y-intercept.
From the above graph, the two lines that contains

are line CE and line BC.
Since, the slope

is negative, line BC is the required line because it is sloping backwards.
We can confirm this by using the point,

and

to find the slope and obtain
