a.
To find: the solution of given pair of linear equations by graphing.
a.
Answer to Problem 3P
No solution
Explanation of Solution
Given information: a pair of linear equation is given as follows-
Graph:
Interpretation: since the graph of both the linear equation is parallel to each other and they will never cross each other.
Hence there is no solution for given pair of linear equations.
b.
To find: the solution of given pair of linear equations by graphing.
b.
Answer to Problem 3P
Infinitely many solutions
Explanation of Solution
Given information: a pair of linear equation is given as follows-
Graph:
Interpretation: since the graph of both the linear equations is same and coincide each other. Hence there is infinitely many solutions for given pair of linear equations.
c.
To state: how can we determine without graphing whether given system of equations has one solution, infinitely many solutions, or no solution?
c.
Explanation of Solution
let a system of equations be as follows-
Then the given system of equations will have only one solution if
The given system of equations will have infinitely many solutions if
The given system of equations will have no solution if
