15/7 or 2 1/7 (same number but the first one is an improper fraction and the other is a mixed fraction) 
        
             
        
        
        
Answer and Step-by-step explanation:
In the equation y = 25x + 100, the format of y = mx + b is being used. This is a very commonly used base for equations in math, especially when it comes to graphing.
In the equation, the m stands for the slope in the equation, and the b stands for the y intercept. Slope can also be found by taking the rise/run of a graph.
So, the slope of this line is 25, and the y-intercept 100.
I have also included the this equation on a graph as well.
I hope that this helps.
