when x=10, y=17
when x=50, y=97
when x=100, y=197

Read what w said carefully
y = 2 x - 3 !!!
for any x, that gives you y
w noticed that all the given points sat in the straight line y = 2x-3

Now the wayt ot figure that out is to take the slope between any two points
m = (7-3)/(5-3) = 4/2 = 2
so if there is a linear relation
y = 2 x + b
now what is b?
when x = 1, y = -1
-1 = 2 + b
so b = -3
now check to make sure that fits all points, then use it.
