What is the resulting ordered pair if the value of the independent variable is 5? f(x) = –2x + 1 a.(–2, 5) b.(5, –9) c.(5, –11) d.(2, 5)

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).
