Well to solve you need to use a formula that says y2 minus y2 divided by x2 -x1 is equal to the slope. So the equation should equal, 10 - 13 / 6 - 2 and that equals -3 / 4, and so the slope is equal to -3/4.
let x be the no. of years it takes to be the same height
9ft=108inches
8ft= 96inches
96+8x=108+6x
2x= 12
x=6
