Answer:
4/1. with an intercept of 5
-2 (-30) - 3y = 42
60 - 3y = 42
-3y = -18
y = 6
A function has a property such as "one input must be mapped to exactly one output." An input is the x-value, and the output is, generally, the y-value. In this set of points above, the input 3 maps to 4 <em>and </em>12, and therefore is not a function.
Answer:

Step-by-step explanation:
For this case we have two points given (-1,6) and (1,5)
And we want to complete the point slope equation of the line:

We need to find the slope and we can use the following formula:

And replacing the info we got:

And then the equation would be given by:

And our final answer would be:
