Answer:

The graph of given inequality is shown below

Step-by-step explanation:

The given inequality is

$2x-5y$

We need to find the graph of this inequality.

The related equation of the given inequality is

$2x-5y=-20$

Table of values is

x y

0 4

-5 2

Y=4x+1<br> Y=-2x-5, help we solve these problems

Stella [2.4K]

$y=4x+1\\
y=-2x-5\\\\
4x+1=-2x-5\\
6x=-6\\
x=-1\\\\
y=4\cdot(-1)+1\\
y=-4+1\\
y=-3\\\\
\boxed{(x,y)=(-1,-3)}$
