Answer:

See explanation

Step-by-step explanation:

Given the equation $3x-4y=12$

A. Create the table of values for at least 4 points.

When $x=0,$

$3\cdot 0-4y=12\\ \\-4y=12\\ \\y=-3$

When $x=2,$

$3\cdot 2-4y=12\\ \\-4y=12-6\\ \\-4y=6\\ \\y=-1.5$

When $x=4,$

$3\cdot 4-4y=12\\ \\-4y=12-12\\ \\-4y=0\\ \\y=0$

When $x=6,$

$3\cdot 6-4y=12\\ \\-4y=12-18\\ \\-4y=-6\\ \\y=1.5$

When $x=8,$

$3\cdot 8-4y=12\\ \\-4y=12-24\\ \\-4y=-12\\ \\y=3$

Thus, the table is

$\begin{array}{cc}x&y\\0&-3\\2&-1.5\\4&0\\6&1.5\\8&3\end{array}$

B. Use the table of values to graph the line on the coordinate plane. Plot given points and connect them with the straight line (see attached diagram).
