You can put this solution on YOUR website! how do you graph:
 ?
Step 1. A relatively easy way is pick two point and plot a line between the two points. Two points could be (0,b) and (a,0) where b is the y-intercept and a is the x-intercept.
Step 2. Let's start with (0,b) where x=0 and y=b. Substitute x=0 into
 or in standard form as 
Divide by -5 to both sides of the equation
 or 
So we have point (0,-4)
Step 3. Let's start with (a,0) where x=a and y=0. Substitute y=0 and solve for x=a.
Divide by 6 on both sides of the equation.
Now we have another point (10/3,0).
Step 4. We now have two points to plot: (0,-4)and (10/3,0) found in Steps 2 and 3. Use these points to draw a line as shown below:
I hope the above steps were helpful.
