The graph shows the relationship between hours spent on video games and hours spent on homework last week for students in Joyce'
s class. Joyce created the following scatterplot and regression line to show this relationship. The fitted line has a yyy-intercept of 232323.

A graph plots Hours spent on homework, from 0 to 24, in increments of 2, versus Hours spent on video games, from 0 to 14, in increments of 2. Dozens of points fall diagonally in a relatively tight, narrow cluster between (0.5, 23.8) and (14.1, 3.1). A regression line falls diagonally through the center of the cluster from (0, 23) to (15, 3). All values estimated.
quita los paréntesis: 4x-5=2+3(x-3) multiplica paréntesis X3, elimina el paréntesis: 4x-5=2+3x-9 calcule: 4x-5= -7+3x mueve los términos y te quedará así: 4x-3x-5=-7
agrupe los términos semejantes: x=-7+5
calcular la suma, y el resultado final sería: x= -2
I’m going to use Pythagorus theorem for his question. // firstly I would do 20^2 + 16^2 = 656 // we them square root that number, so the square root of 656 is 25.61, meaning the missing length is 25.6
