A. infinitely many
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
Solving systems of equations
Step-by-step explanation:
If 2 lines are parallel (same slope, different y-intercept), they would have no solution.
If 2 lines were the same (same slope, same y-intercept), they would have infinite amount of solutions.
