A line passes through the points 2,15 and 6,19 . Write a linear function rule in terms of x and y for this line

Vertical lines: lines that run up and down.  If you are standing up then you are vertical.  On a graph the x-axis has little marks that run up and down or "vertical."  Since the x-axis has lines that run vertical then if you have a point use you x-ordinate (x number).   Therefore; in the point (4, -3), your vertical line is x = 4.

In the point (2, 10), can you determine the vertical line ...

Step-by-step explanation:

Right you figured it out x = 2.

For vertical line just take the other number and write y =.
