How would I approach this problem?

V The scatter PM shows the time spent texting, x, and the time spent exercising, y, by each of 25 students last week. (a) Write an approximate equation of the line of best t for the data. It doesn't have to be the exact line of best t. (b) Using your equation from part (a), predict the time spent exercising for a student who spends 4 hours texting. Note that you can use the graphing tools to help you approximate the line. 9&\\ b '? 9- x a- x x (a) Write an approximate equation of the line of best t. x X Time spent 7" x X y _ exercising 6- x x .
