Thank you in advance for any and all help you provide me with this algebra problem:

PREDICT THE MAXIMUM HEIGHT OF A BICYCLE THAT WEIGHS 21.5 pounds, ALL OTHER THINGS REMAINING CONSTANT.

here is the data provided

WEIGHT, HEIGHT
19 10.35
19.5 10.3
20 10.25
20.5 10.2
21 10.1
22 9.85
22.5 9.8
23 9.79

i tried to graph this and used WEIGHT as the x coordinate and HEIGHT as the y coordinate but i'm truly stumped! what is the next step in the solution please?

What have you been taught to solve these types of problems? Are you supposed to fit "least-square" line through these points?
