A the first answer because the triangles are the same they are just flipped
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)
The common denominator of both fractions is 60.. You can convert 11/12 into 55/60 by multiplying both the numerator and denominator by 5, and you can also convert 7/20 into 21/60 by multiplying both the numerator and denominator by 3. 55/60-21/60= 34/60, simplified to 17/30.
Hope it helped!
