State the gradient of the line parallel to 3y = 5x – 1.

Lydia collected two sets of data one set of data shows an outlier. which set has an outlier, and which number is the outlier?

If a line is defined by the equation y = 5x + 2, what is the slope?

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
