Answer:
x = -11
Step-by-step explanation:
I'm going to assume 80 and 60 are vertical angles so:
x + 51 + 80 + 60 = 180
x + 191 = 180
x = -11
-(-z + 3) equals z - 3
5 = z - 3
z = 8

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
They can split them in half and throw the rest out so no one gets jealous
