What is the value of x when the line crosses the x-axis?
When a line crosses the x-axis, the value of y becomes 0. To find the x-value, you need to solve the equation of the line for x when y = 0.
If you have the equation of the line in slope-intercept form (y = mx + b), you can substitute y = 0 and solve for x:
0 = mx + b
Solving for x:
mx = -b
x = -b/m
Here, x represents the value of x when the line intersects or crosses the x-axis. The slope (m) represents how steep the line is, and the y-intercept (b) represents the point where the line intersects the y-axis.
