Write an explanation for both part a and part b using 3-4 complete sentences. part a: explain how you can determine if a system of equations will have no solution when comparing the graph of the equations. part b: explain how you can determine if a system of equations has no solution by comparing each algebraic equation. be sure that your explanation includes 3 of the 4 words below: parallel, slope, y-intercept, slope intercept form

Step-by-step explanation:

Part A : when comparing graphs : A system of equations will have no solutions (on a graph) when your lines never cross each other. They never cross each other because your lines are parallel.

Part B : by comparing each algebraic equation : A system of equations will have no solution if your lines are parallel. Parallel lines will have the same slope but different y intercepts. Example :

2x - y = 2

4x - 2y = 8

put both equations in slope intercept form

y = 2x - 2

y = 2x - 4

they both have the same slope of 2and the y intercepts are differentmeaning they are parallel lines and have no solutions

its b
