The equation of a line is y= -1/2x - 1 what is the equation of the line that is perpendicular to the first line and passes through the point (2, –5)?

y=2x-9 or D

Step-by-step explanation:

To get the slope of the perpendicular line, you find the negative reciprocal.  The negative reciprocal of -1/2 is 2.

Then, you need to find the y-intercept.  Considering the line has to pass through the point (2,-5), you can use the slope to find that the y-intercept is -9.  

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
