Answer:
The maximum number of times a line can cross the x-axis is one
Step-by-step explanation:
we know that
The equation of a line in standard form is equal to
[tex]Ax+By=C[/tex]
Remember that
The x-intercept is the value for x when the value for y is equal to zero
so
For [tex]y=0[/tex]
substitute in the equation and solve for x
[tex]Ax+B(0)=C[/tex]
[tex]Ax=C[/tex]
[tex]x=C/A[/tex] ----> value of the x-intercept (one solution)
therefore
The maximum number of times a line can cross the x-axis is one
