1. refer to the equation 3x − 4y = 12.
(a) create a table of values for at least 4 points. show your work on how you found the values for each coordinate pair, and validated the points were on the line.

(b) use the table of values to graph the line on the coordinate plane provided on the last page.

The table of values and graph is as attached

Step-by-step explanation:

Pick values for x as follows;

When x=0,substitute value for x in equation 3x-4y=12

3(0)-4(y)=12,

-4y=12, y=-12/4=-3

When x=1,substitute value for x in equation 3x-4y=12

3(1)-4(y)=12,

-4y=12-3, y=-9/4=-2.25

When x=2, substitute for x in equation 3x-4y=12

3(2)-4(y)=12,

6-4y=12, -4y=12-6, -4y=6

y=-6/4=-1.5

When x=3, substitute for x in equation 3x-4y=12

3(3)-4(y)=12,

9-4y=12, -4y=12-9, -4y=3

y=-3/4=-0.75

Values for x and y were plotted on the graph attached
