The scatter plot shows the relationship between the number of car accidents in a month and the number of drivers attending a program on distracted driving. the equation represents the linear model for this data. y=−0.0067x+17 what does the number 17 in the equation mean in this context?

The 17 is called a y-intercept so  when graphing you would find 17 on the y axis. This is your starting point. Then (in this case) you would go down 0.0067 (down since its negative) because that is the slop. You continue that until you have a line :) 

I bolded the answer :)Hope this helps :)

It is 128°

65° + (90-27)=x
65°+63°=128
