Question 1 What line is parallel to y = 3x + 4?

a. 5x + y = 2

b. –3x + y = 4

c. y = 1/3x +

-- Answer -- b

Always put the equation into y–intercept form to find parallel & perpendicular lines

a. y = –5x + 2 => –5 ≠ 3(parallel lines have equal slopes)

b. y = 3x + 4 => 3 = 3 (parallel lines have equal slopes)

c. y = 1/3x + 4 => 1/3 ≠ 3 (parallel lines have equal slopes)
