Nadusha1986 [10]
85% liked => 15% didn't like

30 = 15% of x
30 = 0.15 x => x = 30 / 0.15 = 200. This is the total number of students at the library.

Then 200 - 30 = 170 is the number of students whom did like reading mistery stories.

First find the slope of A.

Slope=(y2-y1)/(x2-x1)=(4-0)/(0--7)=4/7

For a line to be perpendicular to line A, it must have a slope that is the negative reciprocal of the slope of A.  Mathematically:

m1*m2=-1 and in this case the perpendicular line will have a slope of:

4m/7=-1

4m=-7

m=-7/4 

So the slope of the line perpendicular to A is -7/4
