Yes, this is a linear equation.

Explanation:

A linear equation is an equation for a straight line and can be written in the form of y = mx + b, where m and b are constants that determine the slope of the line and the intercept, respectively.

The equation x/2 - y = 7 can be rewritten as y = x/2 -7 and thus fits this pattern. The slope of this straight line is 1/2 and the constant term (y-intercept) is -7.
