The slope of a line is given by:

Plugging the values of the problem we have:

Solving for x we have:

Therefore, x=7.
Change all the x values to negative the new coordinates are :
(-4,3), (-4,6), (-6,3)
Answer:
a) {(3,3),(3,4),(4,5),(4,6)}
Step-by-step explanation:
Given
(a) to (d)
Required
Which is not a function
A relation is represented as:

For the relation t be a relation, then:
where 
This means that none of the x values must be related.
The first relation has 3 repeated as its value of . Hence, (a) is a relation
The opposite of 1/3 = -1/3
the opposite of -7/12 = 7/12
Okay so basically 1 + 5 = 180
and if we know 1 = 124 we can assume 5 = 56
and 5 = 4 SOOOO
4 = 56
