The correct Answer is:
To determine the condition under which the lines represented by the equations \(y = m_1 x + 4\) and \(y = m_2 x + 3\) intersect to the right of the y-axis, we will follow these steps: ### Step 1: Set the equations equal to find the intersection point We start by equating the two equations to find the x-coordinate of the intersection point: \[ m_1 x + 4 = m_2 x + 3 \] ### Step 2: Rearrange the equation Next, we rearrange the equation to isolate the terms involving \(x\): \[ m_1 x - m_2 x = 3 - 4 \] This simplifies to: \[ (m_1 - m_2)x = -1 \] ### Step 3: Solve for \(x\) Now, we can solve for \(x\): \[ x = \frac{-1}{m_1 - m_2} \] ### Step 4: Determine the condition for \(x\) to be positive For the intersection point to be to the right of the y-axis, \(x\) must be positive: \[ \frac{-1}{m_1 - m_2} > 0 \] This inequality implies that \(m_1 - m_2\) must be negative (since a negative divided by a negative is positive). Therefore: \[ m_1 - m_2 < 0 \quad \Rightarrow \quad m_1 < m_2 \] ### Conclusion Thus, the condition for the lines to intersect to the right of the y-axis is: \[ m_1 < m_2 \]
