• Each has a slope of –3 and a y-intercept of –1, which makes the lines parallel.

• Each has a slope of –3 and a y-intercept of –1, which makes the lines equivalent.

• Each has a slope of –3, but one has a y-intercept of 3 and the other has a y-intercept of –1, which makes the lines parallel.

• Each has a slope of –3, but one has a y-intercept of 3 and the other has a y-intercept of –1, which makes the lines equivalent.

Miguel used the graph to represent a system of equations.

Which statement is the best conclusion for Miguel’s system?

• Since the lines do not intersect, this system has no solution.

• Since the lines will intersect at one point, this system has one solution.

• Since the lines will intersect at two points, this system has two solutions.

• Since the lines will intersect at many points, the system has many solutions.
