Solutions to Systems of Equations

How many solutions does the following system of linear equations have:

-3x + 3y = 12

y = x + 4

• The graphs of the equations are lines that intersect at one point because the equations have the same slope and same y-intercept The system has exactly one solution.

• The graphs of the equation are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.

• The graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. The system has exactly one solution.

• The graphs of the equations are parallel lines because they have the same slope but different y-intercepts. The system has no solution.
