Please help me and dont just guess this is hard. A private plane and a jetliner both fly over a park that is at (-2, 2) on the map. The path of the jetliner follows the line y = 1/2 x -3. The private plane flies perpendicular to the jetliner. What is the equation in slope-intercept form of a line that represents the private plane's flight path?

Sherina wrote and solved the equation. x-56=230 x-56-56=230-56 x=174 what was sherina’s error? sherina’s work is correct. sherina only needed to subtract 56 from 230. sherina made a subtraction error when subtracting 56 from 230. sherina should have added 56 to both sides of the equation.
