x-intercept
The x-intercept is a point on a graph where the graph intersects or crosses the x-axis
The x-intercept is a point on a graph where the graph intersects or crosses the x-axis. It is the value of x when y is equal to zero. In other words, it is the value of x at which the function or equation equals zero.
To find the x-intercept, you need to set y equal to zero and solve for x.
Here’s an example:
Let’s say we have the equation y = 2x – 4.
To find the x-intercept, we set y equal to zero:
0 = 2x – 4
Next, we solve for x by isolating the variable:
2x = 4
x = 4/2
x = 2
Therefore, the x-intercept of the equation y = 2x – 4 is x = 2.
Graphically, the x-intercept is the point where the graph of the equation intersects the x-axis. In this case, it is the point (2, 0) on the graph.
