When writing an ordered pair in the Cartesian plane, which coordinate is written first and what does it represent?

You must plot the point (4, -2). Which sequence of moves from the origin is correct?

Use the equation x = 3y - 2 to find y when x = 2.

For the equation $4x+3y=1$, which of the following pairs is a solution?

A table shows that when $x=0$, $y=3$, and when $x=2$, $y=7$. Assuming $y$ depends linearly on $x$, find the linear equation $y=mx+b$, and then compute $y$ when $x=4$.
