Which equation represents a line which is parallel to the line 7y - 4x = -49 a) y= 7/4x+3
b) y= -7/4x+1
c) y=4/7x+7
d) y= -4/7x+4

For what value of x does 4x = (1/8) x + 5?

A(1,1) b(-3,0) c(-4,-1) d(3,-2) drag it to correct position

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
