Algebra-1

Among the given functions, the linear function is .
Here's why:
Linear Function Criteria: A linear function has the general form y=mx+b, where m and b are constants. This form represents a straight line when graphed.

Analysis of Each Function:
A. : This is in the standard linear form y=mx+b where m=2 and b=−7. Thus, it is linear.

B. : This equation is not linear because it involves a square root function, which is nonlinear. Rearranging it to
