Answer:
   (0, 2), (5, 5)
Step-by-step explanation:
The w-intercept is the constant in the equation, so you know immediately that (x, w) = (0, 2) is one point on your graph.
Since the value of x is being multiplied by 3/5, it is convenient to choose an x-value that is a multiple of 5. When x=5, we have ...
   w(5) = (3/5)(5) +2 = 3+2 = 5
So, (x, w) = (5, 5) is another point on your graph.
 
        
             
        
        
        
Pretty sure its 58, because i think you find it by multiplying the 4 inches by 14.5 because that's what each inch represents, so if this is wrong I'm sorry, but I'm pretty sure its 58.
