Answer: Fourth option.
Step-by-step explanation:
By definition, a relationship is a function if and only if each input value (or each x-value) has only one output value (or y-value).
Given the first table:
You can notice that the input values 2 and 3 do not have only one output value. Therefore, this table does not represent a function.
The second table is:
You can notice that the input values 4 and -4 do not have only one output value. Therefore, this table does not represent a function.
The third table is:
You can notice that the input values 6 and 7 do not have only one output value. Therefore, this table does not represent a function.
The fourth table is:
You can notice that each input value has only one output value. Therefore, this table represents a function.
- Slope Formula:
- Slope-Intercept form:
, with m = slope and b = y-intercept.
So firstly, we have to find the slope. Looking on this line, we see that two points that are on this line are (0,3) and (4,0). Plug them into the slope formula and solve as such:
Now we know that the slope is -3/4. Now looking for the y-intercept, we see that it has been provided for us. The y-intercept is (0,3).
<u>Putting our equation together, it is </u>
