Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

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
