Hello there! Slope is rise/run. The formula for finding slope is y2 - y1/ x2 - x1, meaning that you subtract the first x and y-coordinates from the second x and y-coordinates. We'll use the points (0, 3) and (3, 2) for this case. Plug in the values into the formula to get this:
2 - 3 / 3 - 0
Subtract the values in order to get -1/3. There. The slope of the line is -1/3.
        
             
        
        
        
Only one. 8
Divide by 6 on both sides. x = 8. That's it.
        
             
        
        
        
y = number of days
35.50 + 18.25 y  = 163.25
18.25 y = 163.25 - 35.50 
18.25y = 127.75
y = 127.75 / 18.25 
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25
