Help me with the pirates

Answer 1

For Roberts the equation is:

`5y-x=-25`

to we can write it as slope intercept so:

`\begin{gathered} 5y=x-25 \\ y=(1)/(5)x-5 \end{gathered}`

Now we replace x = 5 so

`\begin{gathered} y=(5)/(5)-5 \\ y=1-5 \\ y=-4 \end{gathered}`

So the two points are ( 0 , -5) and ( 5 , -4)

Fo Hookthe equation is:

`2x-5y=0`

In slope intercept is:

`\begin{gathered} 5y=2x \\ y=(2)/(5)x \end{gathered}`

so we replace x = 5 so:

`y=2`

So the two points are: ( 0 , 0) and ( 5 , 2 )

For Elizabeth the equation is:

`y-6=(1)/(2)(x-2)`

and slope intercept:

`\begin{gathered} y=(1)/(2)x-1+6 \\ y=(1)/(2)x+5 \end{gathered}`

now we replace x = 2 so:

`\begin{gathered} y=1+5 \\ y=6 \end{gathered}`

So the coordinates are ( 0 , 5) and ( 2, 6 )

And for Silver the equation is:

`4x-y+6=9`

In slope intercept is:

`\begin{gathered} y=4x+6-9 \\ y=4x-3 \end{gathered}`

now we replace x = 1 so:

`\begin{gathered} y=4-3 \\ y=1 \end{gathered}`

So the coordinates are: ( 0, -3) and ( 1, 1 )

So now you can made the graph of the lines and find the message.
