Answer:
13,92838827718412ft
Step-by-step explanation:
a² + b² = c²
a = 13ft
b = 5ft
169 + 25 = 194
c = √194
c = 13,92838827718412ft
900 - 250 = 650
650 / 250 = 13 / 3 = 2.6 = 260%

solve for "k", to find the "constant of variation",
then plug it back in the y = kx, to get the equation
now
what's is y when x = -1?
well, just plug that in the equation with the found "k" value,
to get "y" :)
