Find the value of k if the graph of y=kx goes through the point b(5,-0.5)

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

its 50 miles away from the starting point

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
