Question

  1. choose the statement that correctly describes how many solutions there are for this system of equations. graph of two lines on a coordinate plane a infinitely many solutions because the slopes are equal and the y-intercepts are equal b exactly one solution because the slopes are equal but the y-intercepts are not equal c no solution because the slopes are equal and the y-intercepts are not equal d exactly one solution because the slopes are not equal

Explanation:

Step1: Analyze the lines' slopes and intercepts

The two lines in the graph are parallel (since they have the same slope). For a system of linear equations \(y = m_1x + b_1\) and \(y = m_2x + b_2\):

  • If \(m_1 = m_2\) and \(b_1 = b_2\), the lines are coincident (infinitely many solutions).
  • If \(m_1 = m_2\) and \(b_1

eq b_2\), the lines are parallel (no solution).

  • If \(m_1

eq m_2\), the lines intersect (one solution).

From the graph, the two lines have the same slope (parallel) and different \(y\)-intercepts.

Step2: Evaluate each option

  • Option A: Incorrect. \(y\)-intercepts are not equal.
  • Option B: Incorrect. Equal slopes with different intercepts mean no solution, not one.
  • Option C: Correct. Equal slopes and different \(y\)-intercepts (parallel lines) mean no solution.
  • Option D: Incorrect. Slopes are equal, so they don't intersect at one point.

Answer:

C. No solution because the slopes are equal and the \(y\)-intercepts are NOT equal
