We see that m is a negative sloping line with a positive y-intercept and a positive x-intercept.

Since D and E are horizontal and vertical lines, respectively, we can immediately eliminate choices D and E.

Simplifying answer A, we have:

A)

y = (-6x + 7)/6

y = -x + 7/6

Since we have a positive y-intercept and a negative slope, answer choice A could be the equation for a line.
