Line wx contains (−1, 2) and (4, 12) line yz contains points (−5, 8) and (2, −6). lines wx and yz are. perpendicular because the slopes are the same. parallel because the product of the slopes is −1. perpendicular because the product of the slopes is −1. parallel because the slopes are the same

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
