Which of the following points lies on the x-axis?

Find the equation of the line through $(1,2)$ and $(4,-1)$ in slope-intercept form $y=mx+b$.

Write the equation in slope-intercept form for the line with slope $4$ that passes through $(\frac{1}{2},-\frac{3}{4})$.

Why does each ordered pair (x,y) that satisfies ax + by = c correspond to a point on the graph of that equation?

Given the linear equation 3x + 2y = 12, find y when x = 2.

Given the equation $2x+3y=12$, compute the $y$-values for $x=0$ and $x=3$, and then verify whether the point $(6,0)$ is on the same line.
