Math Problem Statement
Consider this system of linear equations:
y = –3x + 5
y = mx + b
Which values of m and b will create a system of linear equations with no solution?
m = –3 and b = –3 m = 5 and b = –3 m = 3 and b = 5 m = -3 and b = 5
Solution
To determine which values of and will result in a system of linear equations with no solution, we need to analyze the given equations:
- First equation:
- Second equation:
Condition for No Solution:
A system of linear equations has no solution when the lines are parallel. Parallel lines have the same slope but different y-intercepts.
Step 1: Slope and intercept of the first equation
- The slope () of the first equation is .
- The y-intercept () of the first equation is .
Step 2: Analyze the options for and :
- If the second equation has a slope () equal to , the lines will be parallel if their y-intercepts () are different.
Step 3: Evaluate each option:
-
and :
- Slope: , which matches .
- Intercept: , which is different from .
- Result: No solution (lines are parallel).
-
and :
- Slope: , which does not match .
- Result: Not parallel (intersecting lines).
-
and :
- Slope: , which does not match .
- Result: Not parallel (intersecting lines).
-
and :
- Slope: , which matches .
- Intercept: , which is the same as .
- Result: Infinite solutions (lines are the same).
