Question

What's the maximum number of times a line can cross the x axis ?

Answer 1

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

$Ax+By=C$

Remember that

The x-intercept is the value for x when the value for y is equal to zero

so

For $y=0$

substitute in the equation and solve for x

$Ax+B(0)=C$

$Ax=C$

$x=C/A$ ----> value of the x-intercept (one solution)

therefore

The maximum number of times a line can cross the x-axis is one

Answer 2

If it is a straight line, I would think only once. Unless it curves, etc. (hopefully that helps)
