Question

2x+9<-2y+9 how do I do this

Answer 1

Answer:

Graphing the inequality we have;

Explanation:

Given the inequality;

$2x+9<-2y+9$

Simplifying;

$\begin{gathered} 2x+9<-2y+9 \\ 2x<-2y+9-9 \\ 2x<-2y \\ 2y<-2x \\ y<-x \end{gathered}$

Graphing the inequality, we have;

let us locate the points on the line y=-x and draw a dashed line across it;

$\begin{gathered} y=-x \\ (1,-1),(-1,1),(3,-3) \end{gathered}$

The line will be dashed and the lower part will be shaded (since it is less than);
