Intercept refers to a straight line, which refers to the ordinate of the intersection of the straight line and the Y axis. Intercept is a number, positive and negative. In the linear equation y=kx+b, b is the intercept. Generally speaking, the intercept refers to the longitudinal intercept, and the transverse intercept refers to the abscissa of the intersection of a straight line and the X axis. This concept can also be extended to general curves. The intercept of a straight line can be divided into horizontal intercept and vertical intercept. The horizontal intercept is the abscissa of the intersection of a straight line and the X axis, and the vertical intercept is the ordinate of the intersection of a straight line and the Y axis.

Math:

Mathematics is a subject that studies concepts such as quantity, structure, change, space and information. Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.
