given line: 8y = 2x+ 3
y = (2/8)x + 3/8
y = (1/4)x + 3/8
The slope of the given line is 1/4
a) find the slope of AB and show it is equal to -4
b) midpoint of AB = ( (3+2)/2 , (-1+3)/2 )
or ( 5/2 , 1)
--- show that ( 5/2 , 1) satisfies the given equation by subbing it in to see that the statement is true.
A and B are the point (3,-1) and (2,3) respectively. L is the line 8y-2x-3=0. Show that;
(a) l is perpendicular to AB.
(b) l passes through the mid point of AB
