Last option.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Given the first equation:
You can identify that:
And given the second equation:
You can identify that:
Then, since:
You can conclude that the lines are parallel.
By defintion, when the lines of a system of equations are parallel, the system has No solution and it is classified as "Inconsistent".
