Organize these options into the right categories.

HINT: IF THE LINES HAVE DIFFERENT SLOPES, THEY WILL INTERSECT... ONE SOLUTION

IF THE LINES HAVE THE SAME SLOPE BUT DIFFERENT Y INTERCEPTS, THEY WILL BE PARALLEL... NO SOLUTIONS

IF THE LINES HAVE THE EXACT SAME EQUATION AFTER YOU SIMPLIFY THEM, THEY WILL BE THE SAME LINE... INFINITE SOLUTIONS.

y = mx + b

Groups:

(a) No Solution

,

(b) One Solution

(c) Infinite Solutions

• y=3x-2 and y=-2x+1

• y=2x+5
  and y=2x+7

• y=5x+2 and y-2=5x
