Consider this system of linear equations:y = –3x + 5y = mx + bWhich values of m and b will create a system of linear equations with no solution? m = –3 and b = –3m = 5 and b = –3m = 3 and b = 5m = 5 and b = –3Engenuity answer is m= -3 and B= -3
Accepted Solution
A:
Answer: m = - 3 and b = - 3.
Justification:
A system of linear equations will not have solutions if the two lines are parallel.
Two equations are parallel if their slopes (m) are equal and the y-intercep (b) are different.
Since the given equation is y = - 3x + 5, the value of m of the other equation, y = mx + b, in order to make a system with no solution, needs to be - 3, and the value of b need to be different to 5.
The only pair from the choices that meets that is the first option m = - 3 and b = -3.
