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 $x=4$.

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

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

Which statement correctly describes the roles of the x-axis and y-axis in the Cartesian plane?

Starting from y = -x + 4, generate the ordered pairs for x = -1, x = 1/2, and x = 3. Provide exact fractional or integer y-values and then indicate which of those points lies on the x-axis.
