Answer: Option A
Step-by-step explanation:
A relation between two variables x and y is considered a function if and only if, for each input value x there is only one output value y.
If for an input value 
there are two output values 
and 
then the relation is not a function.
Therefore, to answer this question, identify the table in which each value of x has only one value of y.
You may notice that the option that meets this requirement is option A
Note that in option B, there are two output values 17 and 16 for x = -4.
So this relationship is not a function.
In option C there are 2 output values for x = -5
In option D there are 2 output values for x = -11
Answer:
y = (-3/2)x + 1/2
Step-by-step explanation:
Note that slope intercept form = y = mx + b
Change the given equation so it matches the form:
3x + 2y = 1
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. First, subtract 3x from both sides:
3x (-3x) + 2y = 1 (-3x)
2y = -3x + 1
Next, Divide 2 from both sides:
(2y)/2 = (-3x + 1)/2
y = (-3/2)x + 1/2
y = (-3/2)x + 1/2 is your answer.
