Melanie was asked to find the slope of any line that will be perpendicular to the line "y = -2x + 4". Her response was the slope of any perpendicular line also has to be -2, since perpendicular lines has equal slopes. Is Melanie correct? If she is, explain why. If she is not correct, explain why not, and explain how to get the correct answer.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

i think it will be 4feet long of what i comprehend

6+6=12 so that just tells you what it is one half is 6 the next one is 6
