HELP, HELP, HELP! WILL GIVE BRAIN ! I need someone to answer these 3 simple questions!!!

1. the x coordinate corresponds with the x-axis (horizontally) and the y coordinate corresponds with the y-axis (vertical). The x-value tells how the point moves either to the right or left along the x-axis. This axis is the main horizontal line of the rectangular axis or Cartesian plane.  The y-value tells how the point moves either up or down along the y-axis. This axis is the main vertical line of the rectangular axis or Cartesian plane.

2. To name a point on a graph, count how many units from the origin (0,0) to the left or right you go for the x-value, then count how many units up or down you go to get the y-value.

3. a trend,  that may be an equation, like a parabole, a hyperbole, a simple line with or without inflexion point, or maybe an equation of best fit

f(x)=2/3x-8, which give g(x) the greatest value.
