Maybe try using Photomath it works for me. Good luck
0.7 is the rational number
115 is the slope, and 5 is the y intercept. They tried tricking you by making x turn into m so you think you don't know the slope
The question is saying that the line KJ is approximately equal to the line JN and that the line JN is perpendicular to the line NL. The line labeled LKN is shorter than LNK due to the fact that the line segments in LNK are longer because JN is perpendicular to NL:)
$32.50 would be your answer for all of those :) good luck :)
