Y=3x+1
to find the slope, find the change in y/change in x
7-1=6
2-0=2
6/2=3
3 is your slope
your y intercept occurs when x=0, and that was given to you in the problem
(0,1)
your y int is 1
y=3x+1
$4.55 Add 5.95 and 9.76. You should get 15.45. Then you do 20-15.45=4.55
This is known as "5 take 3", where ordering is not important.
