Which of the following best describes the equation below?

y = 1/5i - 7

A.

both linear and nonlinear

B.

neither linear nor nonlinear

C.

nonlinear

D.

linear

linear → D

The equation of a line (linear) in ' slope - intercept form ' is

y = mx + c

where m is the slope and c the y - intercept

Here the variable is i but the equation is of the form y = mx + c

Thus is a linear equation.
