What is the point where the graph of a line crosses the horizontal axis?
y-intercept
What is the y-intercept for a line?
The point where a straight line crosses the y (vertical) axis.
How do you get the x and y intercept of 3x 4y -24?
The x-intercept is the point where the line crosses the x-axis. 'y' is zero at every point on the x-axis. So to find where the line crosses the x-axis, make 'y' zero, and solve the equation for 'x'. -- The y-intercept is the point where the line crosses the y-axis. 'x' is zero at every point on the y-axis. So to find where the line crosses the y-axis, make 'x' zero, and solve the equation for 'y'. This is the central idea that the following answer calls "zero out". =========================================================X and Y intercepts
What is the definition of the b in y intercept?
b is the y intercept so it is the point (0,b) which is where the line crosses the y axis.
What is the point at which a graph crosses the x-axis?
For a line, this is the x-intercept. For a polynomial, these points are the roots or solutions of the polynomial at which y=0.
