You can put this solution on YOUR website!
show a table of values for -3x + 4y = -12.
Convert equation to the slope/intercept form
-3x + 4y = -12
4y = 3x - 12
divide by 4
y = 3%2F4x - 3
:
We will construct a table using x values of -3 to + 3
Substitute -3 for x and find y
y = 3%2F4(-3) - 3
y = -9%2F4 - 3
y = -9%2F4 - 12%2F4
y = -21%2F4
y = -5.25
do the same for x=-2, -1, 0, +1, +2, +3,
The table
x | y
-------
-3 |-5.25
-2 |
-1 |-3.75
0 |
+1 |-2.25
+2 |
+3 |-.75
:
You can fill in the missing y values
