It's actually called a "translation"
Where you just shift the figure without changing its dimensions.
ANSWER
See explanation
EXPLANATION
The table contains these two points (-4,-3) and (2,-4.5)
The slope of this line is given by;



The y-intercept can be obtained by finding the equation of the line in the form:

We plug in the slope and the point (-4,-3) to find c.
This implies that,



Hence the y-intercept is -4.
The given line is

This is already in the slope intercept form:
The slope is

The y-intercept is c=1
It looks like a scalene triangle but i’m not so sure
I got 45 for x and 135 for z.
X and 3x are supplementary (they equal 180) x+3x=180 — 45+3(45)=180
Then x and z are also supplementary x+z=180 — 45+z=180
(45-45)+z=180-45
Z=135
Sorry if this is wrong. I did my best, hope it helps
Binary Operations
The union of two sets A and B is denoted A ∪ B and
is defined as A ∪ B = {x|x ∈ A or x ∈ B}.
The intersection of two sets A and B is denoted A∩B
and is defined as A ∩ B = {x|x ∈ A and x ∈ B}.
Two sets are disjoint if they have no elements in common,
that is, A and B are disjoint if A ∩ B = ∅.
