x y
1 3
3 17
6 38
10 66
check the slope between each two points:
(17-3)/(3-1) = 14/2 = 7
(38-17)/(6-3) = 21/3 = 7
(66-38)/(10-6) = 28/4 = 7
Clearly the points lie on a line with slope 7.
Since 7*1 = 7, but y(1) = 3, the rule must be
y = 7x-4
I need help for the rule for input 1/output 3, input 3/output 17, input 10/output 66, and input 6/output 38
