Solve the problems. Which correctly explains the number of solutions of the following system of linear
equations?
--3x + 3y = 12
y=x+4
A The graphs of the equations are parallel lines because they have the same slope
but different y-intercepts. The system has no solution
B 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.
C 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.
D The graphs of the equations are the same line because the equations have the
same slope and same y-intercept. The system has infinitely many solutions.
