Question 241622
Express each equation in slope-intercept form. Without graphing the equstions, state whether the system of eqations has exactly one solution, no solution, or an infinite number of solutions. 
x + 4y = -5 
4x + 16y = -20
-----------
The 2nd eqn is 4 times the first, they're dependent.
One eqn with 2 unknowns --> an infinite number of solutions.
--------
x + 4y = -5
y = (-1/4)x - 5/4
