You can't have a negative y
Divide -1 from both sides so now the sign flips sides because you divided a negative
y > -3x +5 (theres a line underneath the >)
Go to the vertical line on the axis and go up to 5
Then, start drawing dots every Down 3, Over one
Hope this helps!

Plot a point on 0,5 on the graph. Then, go down 3 units and right 1 unit. Get a ruler and line up the points. Make sure the line is concrete. Shade everything above the line

Answer:

Error: $lnx^2=ln 3x$ not $ln\frac{3x}{0}$

Solution:x=0 and 3

Step-by-step explanation:

We have to find the error and correct answer

Given: $2ln x=ln(3x)-[ln9-2ln(3)]$

$lnx^2=ln(3x)-[ln9-ln3^2]$

Using the formula

$alog b=logb^a$

$lnx^2=ln(3x)-[ln9-ln9]$

$lnx^2=ln(3x)-0$

$lnx^2=ln(3x)$

$x^2=3x$

$x^2-3x=0$

$x(x-3)=0$

Therefore, x=0 and x=3

But last step in the given solution

$lnx^2=ln\frac{3x}{0}=\infty$

It is wrong this property is used when

$log m-log n$ then

$log\frac{m}{n}$

Hence, the student wrote $lnx^2=ln\frac{3x}{0}$ instead of $lnx^2=ln3x$ and solution is given by

x=0 and x=3
