Graph the system. Tell whether the system has one solution, no solution, or infinitely many solutions. y = - 2x + 1 y = - 2x - 3

Let's try the actual solution of the system

y = - 2x + 1

y = - 2x - 3

Note that the slopes of the graphs of these two lines are the same: - 2.

That means that the lines are parallel to one another.

Only the y-intercepts (1 and - 3) are different.

Since the 2 lines never intersect, the system has no solution.
