Which equation represents a line that passes through (2, –) and has a slope of 3?

y – 2 = 3(x + )
y – 3 = 2(x + )
y + = 3(x – 2)
y + = 2(x – 3)

1. ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2. subtraction property of equality 2. m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90 substitution 3. m∠1 + m∠2 = m∠3 + m∠2 definition of complementary 4. m∠1 = m∠3 given
