Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 * 

 = 67
0.3 * 

 = 30
Divide as usual.
67 / 30 = 2 

So, the answer is 2 1/3.
 
        
        
        
Lets compare both equations so we can explain the reason for it, and see it clearly:
<span>y1 = 5x + 1 
</span><span>y2 = 4x + 2
y1 > y2
</span>5x + 1 > 4x + <span>2
</span>To see why that happens we need to solve for x:
5x - 4x > 2 - 1
x > 1
Therefore, the first equation is greater than the second for values of x > 1
        
             
        
        
        
In this form, slope is simply the coefficient in front of <em>x.</em> Therefore, the slope of this graph is -1/4
