Hello,
The correct answer is B.; (5,-9)
The independent variable is the input of a relation. Therefore, the x value.The dependent variable is the output, y value.
The question informs us that the independent variable is equal to 5. In slope-intercept form (all functions can be written in the form of (x)=mx+b). By knowing x=5, plug the value into the function equation: f(x)=-2+1.
f(x)=-2(5)+1
f(x)= -10+1
f(x)= -9
We are needing the value of the dependent variable, y.
Thus, y=-9.
As a result, if x=5 and y=-9, the ordered pair of resulting in an independent variable equaling 5 is (5,-9).
