Let x=aunt's agethen x-14=Mrs West's ageso we have:60-(x-14)=x-40 simplify60-x+14=x-40 subtract x from each side and also subtract 60 and 14 from each side60-60-x-x+14-14=x-x-40-60-14 collect like terms
-2x=-114x=57------------aunt's agex-14=57-14= 43----------Mrs West's ageck60-43=57-4017=17
Rearrange: 2y = 6 -3x
2y = - 3x + 6
y = -1.5x + 3
Now, substitute, perpendicular lines have the same gradient so:
-1 = -1.5 (2) + c
- 1 = -3 + c
2 = c
equation for new line: y = 1.5x + 2
0.125 sorry if I’m wrong :(
