Question 1166309
If you know that there is a straight line that passes through the points (1,7) and the point (0.4), does this straight line pass through the point (2.9)?
===============
From (0,4) to (1,7) x changes 1, y changes 3
From (1,7) to (2,9) x changes 1, y changes 2
Different slope --> not on the line.
=====================
Use commas in the points,  (2,9) not (2.9)
