A length of wire is cut in the ratio 4.5 What is the length of the first piece if the second is 75m are shared.

please help

first u can notice that the graph is going down right?

then it must be -

so it cant be 2/3 or 3/2

then u are looking for a dot that is Integrates with the horizontal and vertical axis like( 0,-1)

u are going one to the right then going down till u touches the ax again if u notice u will go down -1.5 so the slope is -1.5

-3/2 is -1.5

so the slope is -1.5( -3/2)
