I think what you are looking for is to indicate an ecuation for this. So lets do the procedure: First you need to find the slope of this line. <span>(5 - 6)/(5 + 1) = -1/6 </span> <span>So, The slope of the perpendicular line is the opposite reciprocal, which is </span> <span>+6/1.</span><span>Now we know the slope of the line but still have to find the mid point of the line. </span> That is why we are going to <span>use the mid point equation </span> <span>x = (-1 + 5)/2 = 2 </span> <span>y = (6 + 5)/2 = 11/2 </span><span> </span> <span>(y - 11/2) = 6(x - 2) </span> <span>The last thing you do is rearrange the equation to get y = 6x - 6.5 Hope this is what you were looking for </span>
