Identify two equations from above that represent parallel lines and explain why you choose them Identify two equations from above that represent perpendicular lines and explain why you choose them

parallel : (b) and (g)

perpendicular : (d) and (f)

Step-by-step explanation:

straight line equation : y = mx + c

Lines that are parallel have the the same gradient(m),

(b) and (g) are parallel, both of them has m= 1/2

Lines that are perpendicular will have the product of their

gradient(m) equal to -1. So, m1 × m2 = -1

(d) and (f) are perpendicular, because : -4 × ¼ = -1

Hope I was able to help:))
