3/5 of an hour would be 36 minutes (60/5=12, then 12*3=36). If Jerry read for 20 days, then he would read 36*20 minutes in October, so 720 minutes. If we are finding how many hours, we would divide 720/60, which would be 12. That means Jerry read 12 hours in October, and if he read 8 hours in September, then he read 4 more hours in October than September.

Ugh I’m kinda stuck someone can help me ?

Answer:

To graph this line, move one of the points to positive three on the horizontal (side to side) line and negative six on the vertical (up and down) line. To get a slope of negative 1/2 you move down one point and right two points, and you continue until you reach the edge of the graph. Then you do the opposite on the way up (up one and left two).

Hope this helps!
