The line through the midpoint of and perpendicular to the segment joining points (1, 0) and (5, -2). The answe is x_ _= somethin
guapka [62]
First, you have to find the midpoint of the segment. Using the midpoint theorem, (which is (x1+x2)/2, (y1+y2)/2 ) the midpoint of that segment in (3,-1)

Next find the slope of the segment 1,0 and 5,-2  using rise over run or deltax / deltay which is a fancy way of saying change in x over change in y. 

The slope is 4/2 or 2 
When a line is perpendicular to another the slope is the negative reciprocal so the slope of our new line will be -1/2

Now plug in the coordinate (3, -1)  to find the y-intercept and the equation of that line will be complete


so -1 = -1/2 (3) +b
-1= -1.5 +b
0.5 = b


The final equation will be -1/2x + 0.5 =y

hope this helps:)
