Consider where her camer flew out as the 'origin' of her troubles.... she travels 9+ 7+5+3+1 east from there (25 mi)
and she travels 8+6+4+2 north = 20 mi
y= mx+b m = slope = rise / run = 20/25 = 4/5
y = 4/5 x + b and passes through the point 0,10
10 = 4/5 (0) + b
b =10
y = mx+ b becomes
y = 4/5 x + 10 or y - 4/5 x = 10 or 5y - 4x = 50 or 4x-5y=-50 for the form required
