OpenStudy (<3pandas18):

i need to write an inequality for the raph

OpenStudy (michele_laino):

hint: if you make this change of variable, namely from x, y to X, Y, where X, Y are the new variable: \[\left\{ \begin{gathered} x = X + 5 \hfill \\ y = Y + 1 \hfill \\ \end{gathered} \right.\] then the equation of your graph is: \[\left| Y \right| = \left| X \right|\]

OpenStudy (<3pandas18):

so would it be y=5?

OpenStudy (<3pandas18):

no wait y=x+5-1?

OpenStudy (<3pandas18):

i am so confused

OpenStudy (michele_laino):

you have to replace Y with y-1, and X with x-5 in the subsequent formula: \[\left| Y \right| = \left| X \right|\]

OpenStudy (<3pandas18):

wait ik now y=lx+(-5)l +1?

OpenStudy (<3pandas18):

y=lx-5l+1?

OpenStudy (michele_laino):

the right formula is : \[Y = \left| X \right|\] so after the substitution above, we get this: \[y - 1 = \left| {x - 5} \right|\]

OpenStudy (michele_laino):

therefore, you are right!

OpenStudy (<3pandas18):

y=lx-5l+1?

OpenStudy (<3pandas18):

ooooo ok thnks!

OpenStudy (michele_laino):

correct!

OpenStudy (michele_laino):

please, note that the subsequent formula: \[\left| Y \right| = \left| X \right|\] is wrong
