Find an equation in slope-intercept form for the perpendicular bisector of the segment with endpoints h(–3, 2) and k(7, –5).

Y=7/10x+(-4)
The slope of HK is -10/7, so a perpendicular slope is 7/10
The y intercept of a line with m=7/10 going through the midpoint of HK has a y intercept of -4, therefore: y=7/10x+(-4)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
