Identify an equation in point slope form for the line perpendicular to y equals negative 2x + 8 that passes through -3 and 9

Step-by-step explanation:

Hello:

the equation is : y = ax+b

the slope is a : a×(2) = -1( perpendicular to a line with a slope of 2 because y = 2x+8)

a = -1/2          y=(-1/2)x+b

the line that passes through (-3, 9) : 9 = (-1/2)(-3)+b

b = 9-3/2 = 15/2

the equation is :  y  = (-1/2)x +15/ 2

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
