Question

question 14
which of the following pairs of lines are parallel?
lines with slopes m1=3 and m2=3
lines with slopes m_1=1 and m_2=-1
lines with slopes m_1=0 and m_2=1
lines with slopes m_1=2 and m_2=-2

Explanation:

Step1: Recall parallel line rule

Parallel lines have equal slopes.

Step2: Check each option

• Option1: $m_1=3, m_2=3$ (slopes are equal)
• Option2: $m_1=1, m_2=-1$ (slopes not equal)
• Option3: $m_1=0, m_2=1$ (slopes not equal)
• Option4: $m_1=2, m_2=-2$ (slopes not equal)

Answer:

Lines with slopes m1=3 and m2=3
