Does every linear equation have an x intercept

 i hop this is right.  Intercepts of Linear Equations. The intercepts of a line are the points where the line intercepts, or crosses, the horizontal and vertical axes. The straight line on the graph below intercepts the two coordinate axes. The point where the line crosses the x-axis is called the [x-intercept]  hope this is what you need

The answer is no. Any line parallel to the x-axis (but not the x-axis itself) does not have an x-intercept as it does not cross the x-axis. This is the definition of parallel. For example,
y = 1
y = -1
and in general
y = b where b is a nonzero number

Aand b are correctly balanced reactions. they have the same number of atoms in both sides of the reaction
