The equation y−4=−1/4(x−5) is in the form of y=mx+b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
This problem is a rate times time problem. To find the total amount, you must take the rate per unit of time, and multiply it by the given unit of time
