Is this correct?

y=-3x-4

The y interecept is -4.   This is just a point  (0,-4)  So mark this on the y axis.

now

The gradient is        $$-3\; =\; \frac{-3}{1}$$

Now if a line has a negative gradient this means that the top of it will be on the LEFT hand side of the page.

Starting at the y intercept.   Go up 3 spaces.  Then go side ways 3 spaces in the LEFT (or neg) direction.

Mark the point where you end up.  

Join the points and you have your line.   

You should write the equation of the line on the line  

Good job....you are correct....

Thanks. How do I graph the line?

One method is to just select a value for x and substitue it into the equation to  find y.

Then, select another value for x and substitute that into the equation to find a second y.

Plot both points on a graph and draw a line between them.

Hint.... ( I might use 0 and 1 for the two x values to substitute)....post back if you have trouble

I'm no where near knowing how to do this graph thing. I'm so lost and confused :/

Thanks for that excellent answer, Melody.........I hope "Anonymous" understood it better after that...

Thanks Chris,

I really like it when people ask for clarification.

It means that they are really trying to learn from our answers and that is what we want.  :)

I surely did understand it. Thank you both. 

As for anonymous. My name is Kim and I'm not good at math.
