y= mx + b
-9x +y = -2
You asked:
Solve the system of equations:\[\begin{aligned}y &= m x + b\\-\left( 9 x \right) + y &= -2\end{aligned}\]
MathBot Answer:
The system of equations has infinitely many solutions.
$$\begin{aligned}b &= - \frac{m y}{9} - \frac{2 m}{9} + y\\x &= \frac{y}{9} + \frac{2}{9}\end{aligned}$$\(m\) is a free variable.
\(y\) is a free variable.
