3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
3x + y = 12The x intercept occurs when y = 0. Then, 3x + 0 = 12 : 3x = 12 : x = 4The y intercept occurs when x = 0. Then, (3 x 0) + y = 12 : y = 12.

3x - y = 12 is the same as 3x - 12 = y, or y = 3x - 12.
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
y = 12. It's the transitive property. y = 12 = 3x.
Point slope equation: Y=3X+12

y=3x+12

3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
[ y = -12 ] is.
3x + y = 12The x intercept occurs when y = 0. Then, 3x + 0 = 12 : 3x = 12 : x = 4The y intercept occurs when x = 0. Then, (3 x 0) + y = 12 : y = 12.
3x - 2y = 12 2y + 12 = 3x 2y = 3x - 12 y = 3x/2 - 6 Gradient = 3/2 Y-intercept = -6
