18x - 9y + 3z = 18
First, just to clean it up a bit, divide both sides of the equation by 3.
(This doesn't change the equation or its graph in any way.)
6x - 3y + z = 6
At the 'x'-intercept, 'y' and 'z' are zero:
6x = 6
x = 1
At the 'y'-intercept, 'x' and 'z' are zero:
-3y = 6
-y = 2
y = -2
At the 'z'-intercept, 'x' and 'y' are zero:
z = 6

A linear equation.
It is an equation of a straight line.
3d + 14 = 11 is the equation.
x + 5y = 0Subtract 5y from each side of the equation, just to put 'x' and 'y' on opposite sides.x = -5yThis is interesting. If EITHER 'x' OR 'y' is zero, then the other one is also zero.The only place on the graph where that is true is the origin. So the line goes through the origin,and the 'x' and 'y' intercepts are both zero.
x=3 y=2 z=6
x = ±2
None because the discriminant of this quadratic equation is less than zero.

The result will be a plane that intercepts the x-, y-, and z-axes at +9, +6, and +3, respectively.
x-intercept | -10 y-intercept | 4 slope | 2/5 = 0.4
for the equation:5x + 10y = 20, the two intercepts are:x = 0 , y = 2 or (0,2)y = 0 , x = 4 or (4,0)The graph is a straight line passing through the two intercepts (0,2) and (4,0)

Equations don't have y-intercepts, but their graphs may. The y-intercept of the graph of the equation in this question is 0.7 .
