I think you’d do (5,8) - (1,3) to get (4,5)
So electricity costs 15cents every 1,000 watts used, and if he watches tv for 2hrs every day for a month that’s 60 hours (2*30) And every hour he watches tv it’s 150 watts. They want you to do the 60 hrs times 150watts which is 9,000 (amount of watts he uses in the month) and remember 1,000 watts is 15cents
to find the zeros, set the equation equal to zero
0 = -9x-1
add 1 to each side
1 = -9x
divide by -9
-1/9 =x
