SOLUTION: Use the graphing tool to graph the line. Use the intercepts when drawing the line. If only one intercept is found use it and another point to draw the line. 3x-9=3y Help plea

Question 134276: Use the graphing tool to graph the line.
Use the intercepts when drawing the line.
If only one intercept is found use it and another point to draw the line.
3x-9=3y
Help please!

Start with the given equation

Subtract 3y from both sides

Add 9 to both sides

So the equation is in standard form

Start with the given equation

Let's find the x-intercept

To find the x-intercept, let y=0 and solve for x:
Plug in

Simplify

Divide both sides by 3

Reduce

So the x-intercept is

(note: the x-intercept will always have a y-coordinate equal to zero)

------------------

Start with the given equation

Now let's find the y-intercept

To find the y-intercept, let x=0 and solve for y:
Plug in

Simplify

Divide both sides by -3

Reduce

So the y-intercept is

(note: the y-intercept will always have a x-coordinate equal to zero)

------------------------------------------

So we have these intercepts:
x-intercept:

y-intercept:

Now plot the two points

and

Now draw a line through the two points to graph
graph of through the points

and
