3x - 9y = 27-9y = -3x + 279y = 3x - 27y = x/3 - 3The graph is a straight line, with (slope = 3), and passing through the point (y = - 3) on the y-axis.
Let's simplify: f(x) = 3x-3x, so f(x) =0, so y=0 The graph is a line along the x-axis.
3x + y = c where c is any constant number of your choice.

Get in function form. - 3X - Y = 4 - 1(- Y = 3X + 4) Y = - 3X - 4 ----------------------------solve for X and Y by the 0 out method - 3X - 4 = 0 - 3X = 4 X = - 4/3 --------------- Y = - 3(0) - 4 Y = - 4 -------------- Draw a line linking those points.
That is not an inequality. An inequality must have <, >, <=, >=.
There is no single inequality for this equation. Inequalities could include y-3x-5 > 0 y-3x-5 < 0 y-3x-5 != 0

undefined.
A double inequality is an inequality where there are two signs, as opposed to one.Ex: an inequality could be 3x < 15A double inequality could be 3x < 15 < x + 20If you'd want to solve that double inequality, you split it into to expressions:3x < 15 and x + 20 > 15Then just solve.x < 5 and x > -5-5 < x < 5
A straight line, passing through the point (0,5) with a gradient of -3.
The lines are parallel.

3x<15?
y-3x-3 y=3x+3 A line with a slope of 3 crossing the y-axis at 3.
If 7 > 3x - 2 then x < 3.
heres an example: 3x+4>10 in this case, the answer to this inequality would be x>2
